The functin is displayed n the tp line, and the bttm line displays its current status. The display is nrmally blank and remains s until the r,, r ENT pushbuttn is depressed. Pressing any pushbuttn will display the User Lines screen, and then the Lcal Vltage screen. Pwer Up Screens Each time the cntrl is pwered up, it will briefly display a series f screens that include: Beckwith Electric M-2001C (BASE-T) Serial Number Cntrl Firmware Number Date Time f Day User Lines Screen Blanking The display autmatically ges blank after exiting frm any menu, r frm any screen after 15 minutes f unattended peratin. Manual screen blanking is accmplished by pressing the EXIT pushbuttn. Flashing C CHANGE Prmpt This prmpt, in the bttm right crner f a screen, is enabled by initially pressing ENT. This prmpt indicates that the user can change a setting using the r r pushbuttns t increment r decrement the settings. Values have factry preset increments, such as 0.1 vlt r 1 secnd. Press ENT the secnd time t execute the setting change. ENT Prmpt When the E prmpt appears in the tp right crner f the drag-hand parameter screens, peratin cunter reset screen, and demand metering screen, it indicates that the value f display will reset if the ENT pushbuttn is pressed. 2 1

37 M-2001C (BASE-T) Instructin Bk 2.2 User Interface Cntrls r and Pushbuttns The r and pushbuttns have tw functins. First, they are used t change screens and scrll thrugh selectins. Secnd, they are used t enter new values by incrementing r decrementing the displayed value. The new value is nt stred until the ENT pushbuttn is pressed a secnd time. Pressing the r r pushbuttn fr lnger than ne secnd will cause faster scrlling, either when selecting screens r when selecting setpint values. ENT Pushbuttn The ENT pushbuttn is used t perfrm the fllwing functins: Enter the change mde f a screen Stre a setpint r cnditin in memry Enter an access cde Reset certain status screens When entering an access cde, the ENT pushbuttn will mve the cursr (an underline) t the selected digit lcatin and the r r pushbuttn will change the value. When the final digit is selected, and C is flashing, the new access cde is entered using the ENT pushbuttn. In sme cases, it is desirable t leave a screen withut making a change. In selecting setpints r settings, wait 20 secnds withut pressing the ENT pushbuttn and the C will stp flashing. At that pint, the r and pushbuttns will again change screens rather than scrll the previus setpint number r setting chice. The previus changes f that screen will nt be recrded and the lder setpints r cnfiguratin chices will still be in effect. When setting passwrds, prgrammable alarm functin r user lines in the Cnfiguratin Menu, the 20-secnd time-ut is nt functinal and the user cannt cancel nce a new entry has been started. 2.3 Status Indicatrs RAISE LED The red LED indicates when the vltage is belw the lwer band edge and the timer has started timing fr a tapchanger raise peratin. LOWER LED The red LED indicates that the vltage is abve the upper band edge and the timer has started timing fr a tapchanger lwer peratin. REV PWR LED The red LED will light t indicate when the unit detects reverse pwer flw. OK LED The green LED light will remain lit whenever pwer is applied t the unit and the watchdg circuit indicates the micrcntrller is wrking prperly. LDC LED The yellw LED will illuminate when any nn-zer setting has been entered as LDC Fwd resistance r reactance, r LDC-Z. It will als illuminate when any nn-zer setting has been entered as LDC Rev resistance r reactance with the "Rev Pwer Oper" cnfiguratin set t "regulate in Reverse" and the cntrl in reverse pwer mde. V/RED LED The yellw LED will illuminate when any level f vltage reductin has been invked. This is true fr any vltage reductin prcess whether it came frm an external cntact r any Cm input. EXIT Pushbuttn The EXIT pushbuttn is used t exit frm any screen, causing the display t g blank. If EXIT is selected while the "C" is flashing, the cntrl will exit withut keeping the changed setting. 2 2

In rder t restre frnt panel peratin, the Save Cmm Blck at Pwer Off cnfiguratin setting must be set t Disable. Lcal and remte cntrl may be used at the same time by designating Lcal Mde disabled in the Cnfiguratin menu. Settings Entry Use the r and pushbuttns t scrll t the desired setpint entry screen and press ENT t enter the change mde. A passwrd is required fr entry int change mde, unless the Level 1 passwrd has been disabled. Use the r, and ENT pushbuttns t change the setting. When the cntrl is first energized, the quickest way t prperly initialize the cntrl prir t entering the setpints is t set the real-time clck. This actin will initiate a prmpt frm the cntrl t perfrm a reset peratin fr the fllwing items: Demand Metering Energy Metering Drag Hands Reset Registers Resettable Operatins Cunter It is then easy t prceed with the remainder f the cntrl setup. 3.1 Passwrds Passwrd Access Screens T prevent unauthrized access t the cntrl functins, there are prvisins in the sftware fr assigning up t three passwrds. Tw are fr use with the frnt panel cntrls and ne is fr use with the cmmunicatin interface. The passwrds can be set in the Cnfiguratin Menu. Fr mre infrmatin, refer t the Passwrds sectin f the Cnfiguratin chapter. 3 1

41 M-2001C (BASE-T) Instructin Bk Access Levels General access t read setpints, t mnitr status, t reset drag-hand parameters and the resettable peratins cunter d nt require a passwrd. The Level 1 passwrd, if set, is required t make lcal setting changes including the date and time f day. If the Level 1 passwrd is set t all zers, this request fr a passwrd will nt be seen and changes can be made withut a passwrd. The Level 2 passwrd, if set, is required t make changes t the cnfiguratin, passwrds, and user identificatin. If the Level 2 passwrd is set t all zers, this request fr a passwrd will nt be seen and changes can be made withut a passwrd. The COMM passwrd is fr use with the M-2029A TapTalk Cmmunicatins Sftware. This passwrd prvides secure remte peratin. If the cmmunicatins passwrd is set t all zers in the M-2001C (BASE-T) Digital Tapchanger Cntrl, the cmmunicatins prgram will nt ask fr a passwrd. 8 WARNING: Please recrd all passwrds in a secure lcatin. If the passwrd is lst r frgtten, please cntact the factry. 3.2 Vltage Regulatin Standard Cntrl Settings Refer t the Appendix, Figure A-4. With the Level 1 passwrd, six frward and six reverse setpints are available (see Table 3-1) frm the Setpint Menu. They are: bandcenter, bandwidth, time delay, inverse time, and line drp cmpensatin resistance and reactance fr each directin and Z-cmpensatin. The cntrl will send cmmands t the tapchanger t change taps as needed t hld the vltage within the bandwidth setting as mdified by the line drp cmpensatin settings and by paralleling. The cntrl will nly respnd t an ut-f-band vltage excursin after the timer has reached the time delay setting. The timer can be set as an integrating timer r an instantaneus reset timer upn the vltage return t an in-band cnditin. As an integrating timer, it increments during time utf-band and decrements during time in band, but nt belw zer. Vltage Regulatin Withut LDC When the cntrl is just used t regulate the vltage n the transfrmer r regulatr lw-side bus, the nly input required is vltage frm a line-t-line r line-t-grund VT with a nminal 120 V ac secndary. Bandcenter (BC) The center f the vltage band is adjustable frm 100 t 135 V ac in 0.1 vlt increments (fr example, 120 V ac). Bandwidth (BW) The LTC uses discrete steps and the Bandwidth must have a width that allws at least ne tapchange psitin where the cntrl remains satisfied. T minimize excessive peratins n the tapchanger, this bandwidth is usually set t include tw r three in-band tap peratin psitins. The range is settable frm 1 t 10 vlts in 0.1 vlt increments, and 2 vlts minimum is recmmended. This setting is the ttal bandwidth. Time Delay (TD) The time delay setting is needed t inhibit the tapchanger frm unnecessary peratins n temprary vltage excursins and is cmmnly set at 30 t 60 secnds. The cntrl has tw types f timers fr time delay: definite time and inverse time. The kind f time delay the cntrl will use depends n the setting fund in the cnfiguratin menu called TIMER SELECTION. Bth types f delay will wrk in frward r reverse pwer flw. The inverse time delay will fllw the curve in Figure 3-1, Inverse Time Delay Curve. Inverse Time Example Bandcenter 120 V Bandwidth 3 V Inverse Time Delay Setting 120 s ΔV = (Bandwidth/2) = 1.5 V Vin = 123 V Vltage deviatin in multiples f ΔV = [V in Bandcenter]/ΔV = ( )/1.5 =2 Time delay frm Figure 3-1 = 50% f Inverse Time Delay setting = 60 sec. 3 2

43 M-2001C (BASE-T) Instructin Bk Vltage Regulatin with LDC When it is desirable t regulate the vltage at sme distance frm the transfrmer r vltage regulatr, r in general t raise the vltage during high lad cnditins, the Line Drp Cmpensatin (LDC) feature is used. Tw different LDC methds are available in the M-2001C (BASE-T) Digital Tapchanger Cntrl. A cnfiguratin setpint called LDC Selectin allws the user t select frm either f these methds. The Bandcenter, Bandwidth, and Time Delay functins are set the same as if LDC were nt used. LDC X/R A classical apprach can be used t determine the X/R settings fr the LDC, hwever this assumes a lad center pint and is usually nt applicable t the typical distributin feeder. Fr mre infrmatin, cntact Beckwith Electric fr Applicatin Nte #17. A simpler methd, which will wrk fr mst applicatins, is recmmended. This invlves lking at the lines leaving the statin and determining the reactance/resistance (X/R) rati fr the main line. The reactive and resistive line drp cmpensatin setpints shuld then be entered in this same X/R rati. If the CT and VT phasing crrectins have been made t remve any phase angles between measured vltage and live current, nly psitive values f R and X cmpensatin need t be used. Table 3-2 gives the X/R rati fr varius wire sizes and typical cnductr spacings. By knwing the rati f the maximum expected lad t the present lad, the amunt f vltage cmpensatin needed is fund as shwn in the fllwing example. Example Desired lcal min lad = 120 vlts lcal max lad = 124 vlts Using the fllwing assumptins: Desired Bandcenter = 120 vlts Setting Start with R=0 and X=0 and increase bth values using the rati shwn in the table fr the feeder cnductr. Keeping the X/R rati, increase R set and X set until the difference between the cmpensated vltage and the lcal vltage is 2.0 vlts. This example wuld let the vltage vary frm 119 V at n lad t 125 V at maximum lad taking int accunt the bandwidth. With this simplified methd f LDC setting, the first custmer s vltage will be limited by the upper vltage limit at the highest daily lad, depending n the accuracy f the daily lad prjectin. At the same time, the furthest custmer will receive the highest vltage pssible under the line and lading cnditins. The first custmer prtectin can be set n the cntrl. Refer t the Regulatin Limits sectin f this chapter. Since the daily lad prjectins will likely have a seasnal variatin, the best balance f first custmer t furthest custmer vltage may require seasnal adjustment f the LDC settings. Nte that the settings f R and X cmpensatin are prprtinal t the peak lad prjectin and that new settings can be scaled frm the first setting btained by the experimental prcess just described.

44 Setting The Cntrl 3 LDC-Z The secnd available cmpensatin methd is called Z-cmpensatin (LDC-Z). LDC-Z must be selected in the cntrl cnfiguratin prtin f the menu r sftware and the VOLTAGE RAISE (V R ) setpint must be set in rder fr this feature t be implemented. The LDC-Z applicatin is especially useful n systems where several lines exist with different lad centers where the prper cmpensatin is nt related t any single R & X values as set in R & X cmpensatin. Basically, LDC-Z cmpensatin cnsists f designating a target bus vltage increase (line drp cmpensatin) that crrelates t the magnitude f the cntrl current rather than t the calculatin f input R & X line drp at cntrl current magnitude and angle values. The setting, (V R ), is the calculated line vltage drp (at maximum lad) in the circuit r line that has the highest vltage drp at maximum lad cnditin - rati d t the rated CT utput (200 ma). V R = 0 t 24 vlts in increments f 1 vlt. Example: Calculated vltage drp = 5 vlts at lad level f 150 ma cntrl current. V R setting = 200/150 X 5 = 6.7 vlts (runded) = 7 vlts T calculate the line drp cmpensatin at any given cntrl current level (I): V = I/200 X 7 (setting): If I = 50 ma; V = 50/200 X 7 = 1.75 vlts As with R & X cmpensatin applicatins, the blck raise and deadband settings are used fr first huse prtectin n all circuits r lines. NOTE: Fr additinal infrmatin abut LDC-Z applicatins, cntact Beckwith Electric t btain Distributech Paper 1/27/05, "Maximizing Autmatic Reverse Pwer Operatins with LTC Transfrmers and Regulatrs." 3.3 Vltage Reductin Refer t the Appendix, Figure A-4. The cntrl allws three steps f vltage reductin via external dry cntacts r by serial prt cnnectin. The percentage vltage reductin at each step is adjustable frm 0 t 10% in 0.1% increments. When ne r mre cntacts are clsed, the effect is t shift the bandcenter setpint lwer thus causing the LTC t lwer the vltage. Recgnize that the effective bandcenter may have been raised by line drp cmpensatr actin when the vltage reductin is initiated and that the resultant vltage setting will be the cmbinatin f the tw effects. Nte als that the undervltage blck setting may limit the lwering f vltage, especially if there is little raising f the lcal vltage due t LDC actin. When first initiated, r when a subsequent step f vltage reductin is needed, the cntrl will respnd immediately t the vltage reductin cmmand withut regard t either the intertap time delay setting r the cntrl time delay setting. After the desired vltage reductin, peratin will revert back t nrmal peratin with the time delay. Refer t Sectin 6, Cnnectins, fr cntact cnnectins. Wired SCADA dry cntacts r serial prt cnnectin can be used t prvide stepped vltage reductin as described earlier. Hwever, these shuld nt be used tgether, since the resulting reductin wuld be the cmbinatin f the inputs. 3.4 Regulatin Limits Overvltage Limit & Vltage Runback Refer t the Appendix, Figure A-4. Setpints are available t establish a blck raise limit and vltage runback. The vervltage limit is adjustable frm 95.0 V t V in 0.1 V increments. The vervltage limit must be set abve the upper cntrl band limit. This limit is ne prtin f the First Custmer Prtectr t limit vervltage frm line drp cmpensatin actin during heavy lading. The vltage runback level is the Blck Raise setting plus the Dead Band setting (this establishes the First Custmer Prtectin level.) This deadband shuld nt be cnfused with the cntrl deadband abve and belw the center vltage setpint, which is generally called the cntrl bandwidth. The vltage runback deadband is used t assure that the runback setting is sufficiently abve the upper vltage limit setting t limit hunting. It is adjustable frm 1.0 t 4.0 V in 0.1 V increments, and must be set greater than the vltage change f ne single tapchange, r hunting will ccur. It is suggested that it be set fr apprximately twice the vltage change f ne tap. If the vltage exceeds the runback limit, as might be caused by cmbinatins f LDC actin and lad shifts r by a system disturbance withut LDC actin, the cntrl will immediately call fr an autmatic lwer withut any time delay. The lwer cmmand will cntinue until the vltage is reduced belw the runback vltage limit. After this ccurs, the timer will reset. If the vltage is still high, nrmal 3 5

45 M-2001C (BASE-T) Instructin Bk cntrl actin will bring the vltage dwn t within the nrmal cntrl band. Overvltage blck can be effectively disabled by setting it t 135 V. By setting the runback deadband t 4 V, the runback vltage becmes 139 V which effectively disables the feature. Undervltage Blck Refer t the Appendix, Figure A-4. This limit is adjustable frm 95.0 V V in 0.1 V increments. This limit can be set t limit lw custmer vltage t safe limits and will blck vltage reductin actin that culd cause mtr stalling and ther undesirable lw vltage effects. Undervltage blck can be effectively disabled by setting it t 95 vlts. If the vltage is belw the Blck Lwer setpint, the cntrl will nt respnd t further lwer cmmands. Raise cmmands are nt affected. Operatin f the vervltage limit, vltage runback and undervltage blck is illustrated in Figure 3-2. Crdinatin with Backup Relay The M-2001C (BASE-T) Digital Tapchanger Cntrl prvides the first custmer prtectin functins. Use f a back-up relay, such as the M-0329B, is recmmended since the M-2001C (BASE-T) (r any independent cntrl) cannt be expected t be its wn backup. The back-up relay bandcenter setting is usually set the same as the primary cntrl, with the bandwidth setting 1 r 2 vlts greater than the primary cntrl bandwidth, the blck raise setting 1 vlt greater than the primary cntrl, and the deadband setting 1 r 2 vlts. These settings create a runback level 1 r 2 vlts abve the runback level f the primary cntrl. If primary cntrl peratin is desired first, the blck raise setting and the resulting runback level f the backup realy must be higher than thse f the primary cntrl and the blck lwer setpint must be lwer than the primary cntrl setting. Tap Psitin Blck The Tap Psitin Blck is disabled by setting the Tap Infrmatin screen t the Disable cnditin. Refer t the Appendix, Figure A-5. If the Tap Infrmatin screen is nt disabled, the Tap Psitin blck can be disabled by setting the Tap Limits screen t Disable. When using the M-2025B Current Lp Interface Mdule, a ne-secnd intertap time delay shuld be used, due t the time setting f the mdule. Overcurrent Blck Operatin 8 WARNING: The current input t the cntrl is rated at 0.2 A cntinuus, 0.4 A fr tw hurs, and 4.0 A fr 1 secnd. Refer t the Appendix, Figure A-4 fr the Line Limit I screen f the Setpint Menu. The Line Limit Current setpint is available t blck peratin whenever the current exceeds the setting. Depending n the current scaling chice made in the Cnfigure menu, the setting is adjustable frm 0.2 t 0.64 amps in 0.01 amp increments, when using a 200 ma CT scale. If Curr Transfrmer is set fr 1 A, the setting is adjustable frm 1.0 t 3.2 Amps, and if the Curr Transfrmer is set fr 5 A, the setting is adjustable frm 5.0 t 16.0 Amps. This feature can be used t prtect the tapchanger switch during perids f excessive current. This feature can be effectively disabled by setting the blcking current t 0.64 amps, 3.2 Amps r 16-0 amps, depending n scaling CT chice. 3.5 Pulsed Output When the utput selectin is pulsed, the pulse width can be prgrammed frm 0.2 t 12 secnds, in increments f 0.1 secnds. When the utput is set t pulse and the cntrl is calling fr Raise/Lwer, an utput will turn n fr the preprgrammed time, r until a cunter cntact perates, and then turn ff the utput fr a time perid f 0.5 secnds plus the intertap time delay setting value. When the cntrl is calling fr a Raise/Lwer and n cunter input is applied, the utput will activate fr the full preprgrammed time and deactivate fr 0.5 secnds, plus the intertap time delay. When enabling the pulse feature n an LTC withut a cunter cntact, t prevent hunting, care must be taken t set the ON pulse width less than the time it takes fr a cmplete tap change t ccur, but lng enugh fr the seal-in circuit t be activated. The Intertap Time Delay shuld be lnger than the time it takes fr a cmplete tapchange t ccur. When a cunter input is applied, and there is an intertap delay, the pulse will cease immediately (triac is turned ff) with cunter cntact clsure fr the intertap time delay. After the cunter cntact pens, the intertap timer will start at the end f the time delay. If there is still a Raise/Lwer cnditin, anther pulse will start. 3 6

46 Setting The Cntrl 3 When the nn-sequential input is applied, the Raise/ Lwer timers will reset with the cntact clsure, and a timer cunt will start again. If a Raise/Lwer cnditin is still present, the pulse will start nce mre. 3.6 Applicatin Cnsideratins Sequential/Nn-Sequential/Blcking The cntrl nrmally perates in Sequential Mde. In this mde, the tap change utput is initiated after the time delay timer has timed ut. The tap change utput will remain n until the cntrl senses that the vltage has returned in-band. This permits successive tap changes t be made in a sequential mde with n delay between tap changes. If a delay between successive tap changes is desired, an intertap time delay may be used. This value is set at the Intertap Delay screen in the Cnfiguratin Menu. The value is set frm 0 t 60 secnds and will interrupt tap change utputs fr the preset time after a cunter-cntact clsure is detected by the cntrl's peratins cunter input #1. If the full initial time delay is desired, the cntrl may be used in the nn-sequential mde. This mde is selected by applying a mmentary cntact clsure t the cntrl's nn-sequential peratin/ aut tapchanger inhibit input frm the cunter-cntact circuit r an auxiliary relay cntact. Refer t the Applicatin Guide f the apprpriate adapter panel fr details n implementatin f nn-sequential cntacts. If the clsed cntact supplied t the nn-sequential input is maintained, instead f mmentary, the initial timer will nt time ut fr the duratin f the maintained cntact, and the utputs f the cntrl will be effectively blcked. Intertap Time Delay The intertap time delay may be used in cnjunctin with sequential peratin r pulsed utput. The nrmal peratin f this delay timer is as fllws: nce a tapchange cmmand is initiated, when there wuld nrmally be a cntinuus cmmand (raise r lwer) t run the tapchanger until the vltage has returned t within the band setting, there is nw an intertap time delay initiated between tapchanges. When the intertap time delay is set t zer, it is disabled. When invked by a user wh pssesses Level 2 security access (r abve), the intertap time delay will: 1. Recgnize that a tapchange has ccurred, indicated by the cunter cntact input. 2. Remve the utput signal and wait fr the intertap time delay, even thugh the vltage remains utside the designated vltage band. 3. Cmmand anther tapchange after the intertap time delay has expired, withut regard t the basic time delay setting, if the vltage remains ut f band in the same directin as the previus tapchange. NOTE: The intertap time delay is similar in peratin t nn-sequential peratin, but the tw shuld nt be cnfused. The intertap time delay applies a shrt delay after every tapchange, fr the userselected time delay (0 t 60 secnds). It is enabled via a menu screen. The nnsequential peratin time delay will be the same as that f the basic userselected Time Delay as described at the beginning f this chapter.

Cnfiguring Passwrds The user wh pssesses the current Level 2 passwrd may change any passwrd using fur new numbers. A passwrd is nt required if the Level 2 passwrd has been set t When ENT is pressed while viewing the passwrd at its screen within the Cnfiguratin menu, an underline cursr is displayed under the digit furthest t the right f the passwrd. Each digit is changed by using the r and pushbuttns t select the number. Use the ENT pushbuttn t mve the underline t the left. When the underline is n the far left digit, press ENT and the new passwrd is stred int nnvlatile memry. If a wrng number has been entered, press ENT as many times as necessary and the underline will mve t the digit furthest t the right fr entry f the crrect passwrd. This shuld be dne immediately t ensure that an incrrect passwrd is nt stred in memry. If n key entry is made fr apprximately 15 minutes and the screen ges blank and the digit furthest t the left has nt been entered, the passwrd will revert t the previus ne regardless f digits that have been changed. After a new Level 2 passwrd has been entered, the new passwrd must be used t reenter the Cnfiguratin menu. Be sure t recrd the new passwrd fr future use. When a cmmunicatin passwrd has been cnfigured at the cntrl, the cmmunicatin passwrd allws the user t bypass bth the cnfiguratin and setpint passwrds therwise required by a cntrl. NOTE: The cmmunicatin passwrd is identified as a string #. Therefre, the passwrds "0001" and "1" are nt interchangeable. Each cntrl can be given a unique, 4-digit passwrd ranging frm 0 t If the passwrd has been cnfigured at the cntrl as 0000, cmmunicatin is nt restricted a passwrd des nt need t be identified by TapTalk. The cntrl is shipped with cmmunicatin passwrd disabled (set t 0000). Disabling Passwrds Any ne f the three passwrds can be disabled within the screens f the Cnfiguratin Menu by changing the passwrd t zer (0000). When a passwrd is disabled, its access screens will nt be seen and the passwrd will nt be required. Cnfiguratin Changes Use the r and pushbuttns t display the T Cnfiguratin Menu prmpt and press ENT. The Level 2 passwrd is required fr entry, unless disabled. Use the r, and ENT pushbuttns t change the cnfiguratin. 4.2 User Identificatin Changing User Lines Refer t the Appendix, Figure A-8. The user statin identificatin lines allw the user t uniquely identify the unit. In nrmal peratin, after 15 minutes withut pressing a pushbuttn n the display, the screen will be blank. If the screen is blank, any pushbuttn press will reactivate it and display the User Lines screen. Each line f this display can have up t fifteen ASCII characters. Bth f the lines are factry preset with asterisks. When ENT is pressed at the User Line screen in the Cnfiguratin menu, an underline cursr is displayed under the left-mst digit. Each digit is changed by using the r and pushbuttns t select the ASCII character (the ASCII character list begins with! ). The ENT pushbuttn is used t mve the underline t the next digit. When the ENT pushbuttn is pressed fr the right-hand digit, the new user line is stred int nnvlatile memry. 4.3 Alarm Relays Tw alarm relays are prvided in the cntrl t indicate status. The first is a malfunctin r lss-fpwer alarm. Upn either f these cnditins, a dry cntact will clse indicating that the cntrl is ut f service. This cntact will switch up t 3 amps at 120 V ac. Refer t the Appendix, Figure A-6. The secnd alarm relay is nn-latching and is als capable f switching 3 A at 120 V ac and is user-prgrammable t indicate ne r mre f the fllwing cnditins: Blck-Raise Vltage Limit exceeded Blck-Lwer Vltage Limit exceeded Vltage Reductin f any step is invked Reverse Pwer Flw cnditin is detected Line Current Limit/Delta VAr Reactive Current exceeded 4 2

These are necessary due t the different types f cunter cntacts n varius equipment using these Digital Tapchanger (DTC) cntrls and the effect f wear n lder cunter perating mechanisms. The imprtance f the crrect peratin f the cunter extends beynd mere cunting peratins. One additinal feature f the cntrl is distinct "reverse pwer" peratins depending n pwer flw directin. In additin t nrmal cnfiguratins f "blck" r "ignre" during autmatic reverse pwer detectin, the cntrl may be cnfigured t "regulate in reverse directin" r "return t the neutral psitin." The cntrl includes a pwer directin functin fr detecting the reversal f pwer flw in the regulatr r transfrmer. The active pwer directin is based n the flw f real pwer and is nt cnfused by reactive pwer flw in either directin. The directinal peratin f the cntrl will be reversed whenever the pwer flw reverses t as little as 2% (4 ma) f the nminal 200 ma rating f the cntrl. Fr example, t change frm a nrmal frward pwer t reverse peratin, 4 ma f the real cmpnent f the line current must be detected in the reverse directin. T then revert back t the nrmal frward directin peratin, 4 ma f the real cmpnent must be detected in the frward directin. This establishes an 8 ma "hysteresis" effect t 4 ma frm the riginal 8 ma. Additinally, the cntrl can be "biased" in either the frward r reverse directin depending n circuit r system cnfiguratin. This essentially remves the 2% requirement frm the change t the biased directin. Fr example, a cntrl biased in the frward directin will change t the reverse directin as described abve. It will require nly that the pwer flw be in the frward directin t change back t frward peratin. This biasing reduces the "hysteresis" effect t 4 ma frm the riginal 8 ma. In rder fr the "regulate in reverse directin" r "return t the neutral psitin" t implement prperly, tw prerequisites are required. The first is Tap Psitin Knwledge. Withut knwledge f the tap psitin it wuld be impssible fr the cntrl t run the tapchanger t the neutral psitin. The secnd is surce side vltage. Withut knwledge f the surce side vltage, it wuld be impssible t regulate it. Sme cntrls depend n additinal surce side PTs t supply the surce side vltage t the cntrl. The M-2001C (BASE-T) cntrl uses a "keep track" methd f tap psitin knwledge fr all single phase regulatrs t determine the needed values autmatically. The "Keep Track" methd f tap psitin knwledge is incrprated int the cntrl fr single phase regulatrs with a range f +/ 16 taps with a central neutral psitin; where the mtr pwer surce fr manual, autmatic, and external (SCADA) initiated tap changes is the same as the mtr pwer input t the cntrl and with peratinal cunter and neutral psitin cntacts. The internal algrithms maintain an uninterrupted knwledge f the present tap psitin, and calculates the surce side vltage using that infrmatin. The cntrl als uses the infrmatin n Type A r B regulatrs and typical regulatr impedances in the determinatin f surce vltages. 4.5 Crrectin Factrs VT Rati Crrectin Refer t the Appendix, Figure A-5. The peratin f sme regulatrs is such that the internal VT des nt prvide the desired vltage rati. In these cases, it is desirable t crrect the VT secndary vltage t a 120 V ac reference base. This change is easily made in sftware, eliminating the need fr a multitap sensing transfrmer. CAUTION: The use f a vltage crrectin factr is incrprated in the calculatin f primary quantities in the cntrl, and errneus values will be displayed and recrded if the VT crrectin factr is nt included in the PT multiplier. The crrectin is derived frm infrmatin prvided by the regulatr riginal equipment manufacturer (OEM). The numerical value f the crrectin is the value, in vlts, required t adjust the VT nminal secndary vltage t vlts. The crrectin range is ±15 vlts in 0.1 vlt increments. NOTE: The maximum allwable cntinuus VT secndary vltage is 140 vlts. The crrectin is made nly in sftware. As a result, the value f V LOCAL read n the cntrl display will differ frm that measured at the vltmeter test terminals by the percent f the crrectin vltage. 4 3

51 M-2001C (BASE-T) Instructin Bk CT/VT Phase Shift Refer t the Appendix, Figure A-5. The cntrl will recgnize frward and reverse pwer flw t the lad. With the CT and VT (reference) signals inphase fr unity pwer flw t the lad, it will prperly calculate line drp cmpensatin. Depending n the cnnectin f the CT and VT, the phasrs may nt be in-phase. If this is the case, the phase shift can be crrected in sftware. The usual characteristics f three phase systems nly allw multiples f 30 phase shifts. The cntrl, therefre, has a range f 0 t 330 in 30 increments. By cmparing system perating cnditins with pwer flw directin and pwer factr as shwn n the M-2001C (BASE-T) Tapchanger Cntrl, imprper phase shift can be determined. An incrrect cnnectin may be reslved using well-knwn phasr methds. The fllwing prcedure may be useful t check the chice f crrectin r even t determine the crrectin by trial and errr: 1. Put the transfrmer r regulatr n manual cntrl. 2. Determine the Watts and VArs lad n the transfrmer r regulatr frm ther metering. 3. Read the Watts and VArs indicated by the cntrl, and make certain that they are f the same sign and rati f magnitudes as btained frm the external readings. 4. If nt, change the crrectin in 30 increments until the cntrl and external readings are in best agreement. When tw single-phase regulatrs are cnnected in pen delta, the current signals will be ut-f-phase with the vltage signals. Fr ne regulatr, the current will lead the vltage by 30 and is called the leading regulatr. Fr the lagging regulatr, the current will lag the vltage by 30.

Althugh the cntrl peratin is nt affected, errneus values will be displayed and recrded if the VT crrectin factr is nt included in the PT multiplier. Refer t the Appendix, Figure A-5. Primary quantities are displayed when vltage and current multipliers are set int the cntrl. The vltage multiplier is: V mult = V pri /(V sec + V crr ) Fr a VT rati f 7620/117 V and a vltage crrectin f 3 V, the multiplier is: V mult = 7620/( ) = 63.5 The vltage multiplier setting range is frm 0.1 t 3260 in 0.1 steps. The current multiplier is the value f the line CT primary rating divided by 0.2 A. Fr a CT primary rating f 1000 A, the multiplier is: CT mult = 1000/0.2 = 5000 The current multiplier setting range is frm 1 t in 1.0 steps. Bth multipliers are entered in the Cnfiguratin menu. 8 WARNING: The current input t the cntrl is rated at 0.2 A cntinuus, 0.4 A fr tw hurs, and 4.0 A fr 1 secnd. NOTE: The current transfrmer selectin in the Cnfigure menu nly changes the scaling factr fr current reading and setting. 4.7 Tap Infrmatin The M-2001C (BASE-T) Digital Tapchanger Cntrl tap psitin infrmatin applies t many different cnfiguratins f tapchangers, e.g., 16 taps, 1 t 17 taps, 10 taps, 1 t 33 taps, etc. Tw cnfiguratin pints, Tap Min and Tap Max, are assigned t allw the user t select the range f a specific tap changer. The Tap Max range is 0 t 33 taps, and the Tap Min range is 33 t +29 taps. The user is able t prgram the cntrl t select the methd f tap psitin knwledge r t disable this feature. Table 4-1, utlines the eight selectins available fr the Tap Infrmatin screen. Psitive tap psitin knwledge frm external input is nt available when the Cntrl Pwer Backup Input ptin is enabled. 4 4

This feature allws the cntrl t keep track f the present tap psitin. The Reg Internal setting is selected fr this methd. 8 WARNING: D nt rely n the tap psitin indicatin n the M-2001C (BASE-T) Tapchanger Cntrl display fr neutral psitin when bypassing vltage regulatrs. The mtr pwer surce fr the manual, autmatic, r external (SCADA) initiated tap changes must be the same as the mtr pwer input t the cntrl. The peratins cunter and neutral light circuit shuld be peratinal. The cunter input and pwer surce is required fr detecting tap changes and determining directin f the tap change. Cnnecting a regulatr neutral tap psitin indicating cntact t the cntrl will reset the tap psitin t neutral each time the tap ges thrugh the neutral psitin. It is recmmended that the indicated tap psitin be cmpared t the mechanical tap psitin indicatr at regular intervals, and that the indicated value be crrected, if necessary. The tap psitin stred in memry is nt affected by a lss f pwer. The tap psitin recrd is checked and crrected t neutral, if necessary, with the clsure f a neutral cntact (when the neutral tap psitin cntact is cnnected t the cntrls). CAUTION: When the keep-track tap psitin methd is used, it must be calibrated fr prper vltage cntrl with reverse pwer peratin. If desired, the keep-track feature can be disabled in which case the screen will indicate Disabled. The user initializes the cntrl at a given, knwn, tap psitin upn installatin, by selecting Reg Internal in the Tap Infrmatin screen in the Cnfiguratin Menu and perfrming the fllwing steps: 1. Determine the actual tap psitin frm the external tap psitin indicatr n the regulatr. 2. Scrll thrugh the display t the Tap Calibrate screen in the Cnfiguratin menu. Press ENT. A flashing C indicates that the cntrl is ready t accept data. Press the r r pushbuttn until the crrect tap psitin is displayed. Press ENT again. The tap psitin is nw calibrated t recgnize all subsequent peratins s as t keeptrack f the present tap psitin. 4 5

53 M-2001C (BASE-T) Instructin Bk 3. The present tap psitin is indicated in the Status Menu at the Tap Psitin screen. Or, if the neutral tap psitin cntact is cnnected t the cntrl, run the regulatr t neutral as shwn by the tap psitin indicatr n the regulatr. The cntrl will recgnize the neutral light signal and set the tap psitin accrdingly. The keep-track prcedure recgnizes tapchanges cmmanded via manual, autmatic r external (SCADA) cntacts. The pwer surce fr the manualr SCADA-initiated tapchanges must be the same as the mtr pwer surce used fr the autmatic tapchangers. The keep-track psitin knwledge is based n the detectin f a clsed switch (manual r autmatic), and feedback frm the peratin cunter input. The methd by which Keep Track is achieved is as fllws: The cntrl includes tw Zer Vltage Detectin (ZVD) circuits. These circuits individually mnitr the AC vltage acrss the internal raise and lwer triacs. This is dne since any external raise r lwer cntacts r manual switches have t be placed in parallel with the triacs t run the tapchanger mtr. When the triacs (r any cntact paralleled acrss the triacs) clses, the vltage measure decreases t almst zer. When a cunter input event is received while the raise circuit is activated, the Keep Track will increment the tap cunt by ne. When a cunter input event is received while the lwer circuit is activated, the Keep Track will decrement the tap cunt by ne. The cunter input event varies by manufacturer. In mst cases a cunter event is defined by the cunter input receiving an "pen-clse-pen" event. This is prperly interpreted by the cntrl as a single event when the Operatin Cunter cnfiguratin screen is set t the times-ne (X1) ptin. This terminlgy is a leftver frm the days f electrmechanical cunters where an pen-clsepen event wuld register as ne event. It is wrth nting that the cunter input will nly recgnize the event if the secnd pen takes place within 175 ms f the initial transitin frm pen t clse. This is because sme tapchange mechanisms perate in the 400 t 500 ms range, which requires limiting the time windw fr cmpletin f the pulse. The secnd mst likely cunter event is an penclse r clse-pen transitin. In effect, the cunter cntact perfrms ne-half f the previus peratin and perfrms the ther half n the subsequent tapchange. Since the electrmechanical cunters used t recrd these events were called times-tw (X2) cunters, that name is the ptin selected in the Operatin Cunter cnfiguratin screen. The times-tw cnfiguratin is mst ften fund in Siemens prducts. A third ptin has been added t the M-2001C (BASE-T) cntrl, which includes cnfiguratin ptin called Cunt Windw. It has a secnd cnfiguratin screen assciated with it which is called the Cunter Time Windw. This parameter is user-selectable between 0.5 and 10 secnds. The cunt windw bserves any and all activity n the cunter cntacts and recrds ne event during its pen windw, regardless f hw much switch activity r nise it registers. The cunter time windw shuld be set fr a time perid less than the characteristic time lapse between successive tap changes. Half f the characteristic time is prbably a gd starting pint. This feature electrically de-bunces the nisiest cunter cntacts. If the tapchanger reaches the mechanical tap limits f peratin, ( 16), limit switches pen up the apprpriate circuit s the cntrl cannt frce a raise abve +16, r frce a lwer belw 16. This is ptentially cnfusing t the ZVD circuits, since they can see zer vltage n the utput with a clsed triac and als see zer vltage n the ther utput due t an pen limit switch. When this cnditin is encuntered, the cntrl can nly make a best guess f which peratin really ccurs and mves ne step in the directin f neutral, which shuld be away frm the side with the pen limit switch. An additinal feature is the neutral zer feature. When a regulatr passes thrugh the neutral psitin, a neutral cntact clses. This is mst ften used t drive a neutral light that is an indicatr that the mechanism is in the neutral psitin, and it is safe t bridge the input and utput f the regulatr because they are at the same vltage. Upn detectin f a neutral circuit clsure, Keep track resets the tap psitin t neutral t resynchrnize the circuit. 4 6

54 Cnfiguratin 4 Tap Psitin by Psitive Knwledge (Current Lp) Real Tap knwledge in the M-2001C (BASE-T) is btained frm an INCON 1250 and Selsyn psitin transducer. Many variatins f the device were made, but the cnfiguratin adpted by INCON was the "five-wire" cnfiguratin. The five-wire system uses three wires t drive three statr windings cnnected in wye. The remaining tw wires are cnnected t bth ends f a single sense cil, munted n the rtr. The INCON 1250 decdes cmplex amplitude and phase infrmatin t determine the shaft's rtatinal psitin. The 1250 then has t accurately scale the infrmatin t a prgrammed number f taps with knwn start and stp pints. The 1250 then cnverts the infrmatin int an analg current value in any ne f fur current ranges. The current signals are cnditined by the Beckwith M-2025 befre being sent t the M-2001C (BASE-T) as an analg vltage signal. The M-2001C (BASE-T) then re-cnverts the analg signal t digital tap psitins. Cnnectin f the ptinal M-2025B will require either a B-0752 (5 pin t 6 pin) r B-0753 (6 pin t 6 pin) interface cable. See M-2025B Specificatin fr details. The transfrmer (XFMR) and regulatr (REG) external setting is fr use with the Psitive Knwledge (current lp) system, except REG #3, which uses the vltage divider methd. Selecting either XFMR r REG will determine which screens are disabled, and then selecting either #1, #2, r #3 will depend n the utput current r vltage signal frm the Tap Psitin mnitr. Table 4-1 utlines the ptins available fr the Tap Infrmatin screen. When using a resistance t current transducer with an internal tap, fitted t supply a current lp t the M-2025B Current Lp Interface Mdule, the XFMR EXTERNAL#3 selectin in the TAP INFO menu must be selected (e.g., Crmptn Instruments mdel 253-TRTU, 1 17 taps, 400 Ω each, 1 internal tap fitted). The user initializes the cntrl at a given, knwn, tap psitin upn installatin, by perfrming the fllwing steps: 1. In the Tap Infrmatin screen in the Cnfiguratin Menu, select any External selectin. 2. Determine the actual tap psitin frm the external tap psitin indicatr. NOTE: 3. Scrll thrugh the display t the Tap Calibrate screen in the Cnfiguratin menu. Press ENT. A flashing C indicates that the cntrl is ready t accept data. Press the r r pushbuttns until the crrect tap psitin is displayed. Press ENT again. The tap psitin is nw calibrated t recgnize all subsequent peratins f the tap psitin f the tapchanger. 4. The present tap psitin at which the tapchanger is perating is indicated in the Status menu at the Tap Psitin screen. T btain accurate calibratin, it is suggested that the calibratin shuld be perfrmed near the neutral tap fr 0 t 1, 0 t 2 and 4 t 20 ma, and at tap psitin 8 R r 8 L in the case f 1 t +1 ma range. Vltage Divider NOTE: The tap psitin calibratin must be perfrmed at r abve the 4 raise tap, but t btain the best accuracy, it shuld be calibrated at r abve the 8 raise tap. The psitive knwledge by vltage divider methd (REG External #3) is nly fr use n a regulatr that has +/ 16 taps, a vltage divider tap psitin sensr, and a separate raise/lwer utput. The Tap Max and Tap Min can nly be set t 16 raise and 16 lwer, respectively, while in the REG External #3 tap mde. The vltage divider methd is designed t read a tap psitin sensr that cntains 18 resistrs in a vltage divider netwrk. Each tap psitin will give a specific utput vltage frm the tap psitin sensr. The vltage frm the sensr will nly be read int the M-2001C (BASE-T) cntrl nce ne (1) secnd has elapsed after the cunter input has tggled. The tap psitin sensr will nt be read again until anther tap change ccurs, causing the cunter input t tggle nce mre. Als, an external input t the cntrl will be read t determine if a raise r lwer cnditin exists. The raise/lwer input and the vltage frm the divider netwrk will be used t determine what psitin the tap is n. 4 7

55 M-2001C (BASE-T) Instructin Bk 4.8 Reverse Pwer Operatin Detecting Reverse Pwer Reverse pwer flw exists whenever the real cmpnent f the line current changes directin frm frward and remains until anther reversal t fward pwer flw ccurs. The cntrl reliably determines pwer directin with as little as 2% f the real cmpnent f the nminal 200 ma line current (4.0 ma). Pwer Directin Bias Cnfiguratin The Pwer Directin Bias Cnfiguratin screen cntains three settings t determine hw the cntrl will switch between frward and reverse pwer peratin. The three settings are N Bias, Frward Bias, and Reverse Bias. "N Bias" Setting When the Pwer Directin Bias functin is set t "N Bias", the cntrl applies an 8 ma hysteresis band with a bandcenter f 0 lad current (+4 ma t 4 ma) t switch between frward and reverse pwer. The cntrl will switch frm frward pwer t reverse pwer when the lad current exceeds 4 ma (reverse directin). The cntrl will switch frm reverse pwer t frward pwer when the lad current exceeds +4 ma (frward directin). "Frward Bias" Setting When the Pwer Directin Bias functin is set t "Frward Bias", the cntrl applies a 0 ma t -4 ma hysteresis band t switch between frward and reverse pwer. The cntrl will switch frm reverse pwer t frward pwer when lad current is P 0 ma (frward directin). The cntrl will switch frm frward pwer t reverse pwer when the lad current exceeds 4 ma (reverse directin). "Reverse Bias" Setting When the Pwer Directin Bias functin is set t "Reverse Bias", the cntrl applies a 0 ma t +4 ma hysteresis band t switch between frward and reverse pwer. The cntrl will switch frm frward pwer t reverse pwer when lad current is O 0 ma (reverse directin). The cntrl will switch frm reverse pwer t frward pwer when the lad current exceeds +4 ma (frward directin). Upn detectin f pwer reversal, after a 5 secnd delay, the cntrl will perate in the selected mde. The perating mde is selected frm the fllwing ptins: Ignre The cntrl will take n different actin than in the frward directin. It essentially des nt use the pwer directin in the cntrl decisins. This is the same as a cntrl which des nt have pwer directin knwledge. This mde is intended fr use n distributin systems which have the pssibility f pwer reversal because f distributed generatin (DG) n the feeders. In these applicatins, the DG usually des nt have the capacity t cntrl the vltage with the mre pwerful system intact. The cnditin required fr DG t cntrl the vltage is the generatin and transmissin f large amunts f VArs thrugh the line impedance back twards the system surce. Usually tw items prhibit this actin: 1) the ability f the DG t generate thse amunts f VArs and 2) the cntractual bligatins enfrced by many utilities that the DG nly affect KWs n the system. Blck Inhibits autmatic tapchange peratin. This lcks the tapchanger n the tap psitin in use at the time reverse pwer flw is detected. It is the recmmended setting fr independent pwer prducers r in situatins when reverse pwer flw is nt expected. The cntrl will revert t nrmal peratin when frward pwer flw resumes. Regulate REV (single-phase regulatrs nly) The cntrl will detect reverse pwer flw and regulate accrding t reverse pwer settings as selected in the Setpint Menu. With tap psitin knwledge, the cntrl calculates the surce-side ptential withut the use f a surce side VT. This feature is designed fr use with feeder vltage regulatrs which cntinue t perate in a radial mde after system switching causes the pwer flw reversal. The surce vltage is calculated by knwing the lcal vltage, the lad current, and the tap psitin using a presumed regulatr impedance. That impedance is a functin f the tap psitin. The calculated surce vltage is nly valid with a 5/8% step-vltage regulatr. With the cntrl recgnizing reverse pwer flw, the fllwing ccurs: The REV PWR LED is illuminated. Reverse pwer setpints are used. Surce vltage is calculated and mtr utput cmmands are reversed. Fr example, when the vltage is high, the cntrl raises the tap thereby lwering the vltage and a lwer is indicated n the frnt panel LEDs. 4 8

56 Cnfiguratin 4 Return t Neutral T use this feature, a cunter input must be prvided, and ne f the tap infrmatin mdes must be enabled. The Return t Neutral feature will cause the tap psitin t be driven t neutral when reverse pwer is detected. Tap psitin will be driven t neutral regardless f the vltage r currents present at the cntrl. Once neutral is reached, the tap psitin will remain unchanged as lng as reverse pwer is present. Nrmal peratin will resume when frward pwer is detected. This mde is intended as a safe respnse t a pwer reversal n a system which can have cnflicting situatins. As described earlier, a radially perating system with reverse pwer shuld be set t "Regulate Rev." Hwever, if a DG causes a pwer reversal, the prper setting is usually "Ignre". In an applicatin where bth cnditins are pssible and it is nt pssible fr the cntrl t determine the cause f pwer reversal, the prper setting f "Return t Neutral" is advised. 4.9 Parallel Operatin Refer t Figures 4-1, 4-2, 4-3 and t Appendix A, Figure A-8. The user with access t the Cnfiguratin Menu may select the circulating current methd f paralleling LTC transfrmers, r disable the feature. If the ptinal ΔVAR 1/ΔVAR2 methds were purchased, they may als be selected. Paralleling by the circulating current methd r the ΔVAR1 methd invlves a cnfiguratin in which each M-2001C (BASE-T) Tapchanger Cntrl is used with a Beckwith Electric M-0115A Parallel Balancing Mdule. The cntrl is prvided with a current input which is representative f the circulating current between tw r mre LTC transfrmers perating in parallel. Paralleling by the ΔVAR2 methd des nt use the M-0115A Parallel Balancing Mdule. Instead, the tw lad currents are brught int the cntrl, and the actual ΔVAR's which exist between the paralleled transfrmers is calculated internally. When using the ΔVAR2 methd, the cntrl's lad current input is t be cnnected t the lad current CT f the transfrmer which is cntrlling the tap psitin. The cntrl's circulating current is t be cnnected t the lad current CT fr the ppsite paralleled transfrmer. The measured vltage the M-2001C (BASE-T) cntrls n each f the transfrmers will be biased in such a way as t attempt t minimize the circulating current between the tw. In the case f ΔVAR, the tap psitins will minimize the difference in VArs frm each transfrmer. The sensitivity f the cntrl r the amunt f cntrl setpint bias fr a 200 ma circulating current is 24 V. Fr circulating current applicatins, that is a 24 V setpint shift fr 200mA f ttal circulating current intput. Fr ΔVAR1 applicatins, that is a 24 V setpint shift fr 200 ma f reactive circulating current, and fr ΔVAR2 applicatins, that is a 24 V setpint shift fr 200 ma f calculated reactive current difference between transfrmers. (ΔVAR2 is nly applicable fr tw parallel transfrmer applicatins.) Fr applicatins with lw transfrmer impedances, the circulating current r VArs per tap difference is greater than in applicatins with high transfrmer impedances. This creates a need fr a methd t adjust the sensitivity f the cntrl accrding t the system applicatin. On the circulating current applicatin methd and the ΔVAR1 applicatin methd, this is accmplished with a sensitivity adjustment n the M-0115A Parallel Balancing Mdule (see the M-0115A Instructin Bk.) On the ΔVAR2 applicatin methd, which uses n M-0115A mdule, a cntrl setting is prvided t accmplishment the sensitivity adjustment. NOTE: In all M-0115A applicatins, the M-0115A sensitivity settings shuld be equal n all paralleled transfrmers. In all ΔVAR2 applicatins, the sensitivity settings shuld be equal n all paralleled transfrmer cntrls. Exclusively fr the ΔVAR2 methd, there are three functins activated and set in the Cnfiguratin menu fr prper peratin: ΔVAR2 Sensitivity, ΔVAR2 Reac Limit, and ΔVAR2 I Rati. When the ΔVAR ptin has nt been purchased, these input screens will be disabled. The ΔVAR2 Sensitivity ranges frm 4.0 t +4.0, as did the M-0115A adjustment. At a ΔVAR2 Sensitivity setting f 0.0, 100% f calculated reactive current difference will be used t bias the setpint. At a setting f 4.0, nly 50% f the calculated reactive current difference will be used t bias the setpint, making the cntrl less sensitive t the circulating current. At a setpint f +4.0, the bias will be adjusted by a value f 200% f the calculated reactive current difference, making the cntrl mre sensitive t the system current. 4 9

57 M-2001C (BASE-T) Instructin Bk The ΔVAR2 Circ Limit I setpint establishes a limit n the calculated reactive current difference between transfrmers. The settings range frm 5 ma t 200 ma in 1 ma increments. If the calculated reactive current difference reaches this setpint, the peratin f the cntrl will be blcked and the alarm utput functin will be activated, if enabled. The purpse f this limit is t stp any runaway cnditin. This feature is required t replace the M-0127A vercurrent relay used in the circulating current and ΔVAR1 applicatins. NOTE: Care must be taken in setting the ΔVAR2 Circ Limit I, t ensure it is high enugh t allw a tw r three tap difference frm ptimum in transfrmers befre perating. Sme knwledge f system impedances are useful in determining this setting, but the current difference may als be tested fr immediate system cnditins by reading the current change when ne tap is changed n either transfrmer. The ΔVAR2 I Rati is used t adjust the sensitivity t the line current input versus the circulating current input (ppsite transfrmer lad current) t cmpensate fr unequal CT ratis between transfrmers. Fr prper peratin with a rati setting f 1, the rati f the CT ratis must be equal t the rati f the transfrmer ratings (CT1/CT2=MVA1/ MVA2). Example: A 20 MVA transfrmer is being paralleled with a 15 MVA transfrmer. If the CT ratis are 2000 A and 1500 A t 0.2 A, n cmpensatin wuld be required (bth transfrmers are fully laded when the CT utputs are 200 ma.) Hwever, if they each had 2000 A t 0.2 A CTs, the ΔVAR2 I Rati n the 20 MVA transfrmer cntrl shuld be 1.34, and the ΔVAR2 I Rati n the 15 MVA transfrmer cntrl shuld be The settings fr this rati are 0.50 t 2.00, in 0.01 increments. When the setting is 0.50, the cntrl will be 0.50 times as sensitive t the VArs frm the circulating current input versus the lad input current. The default setting fr the sensitivity is 1.00, indicating the rati f the CT ratis are equal t the rati f the transfrmer ratings. This feature can als be used t replace the need fr auxiliary transfrmer fr matching transfrmer CT ratis. N crrectin is necessary t cmpensate fr impedance differences in the transfrmers with ΔVAR peratin. Fr ΔVAR2 applicatins, paralleling will be disabled if either current input drps t less than apprximately 5 ma r if a neutral input is present. When ΔVAR2 peratin is cnfigured, the nrmal neutral input is directed t this duty rather than the nrmal neutral light peratin. It is highly recmmended that this input be cnnected t perate whenever any breaker pens which islates the transfrmer frm parallel peratin. The general paralleling schemes fr tw and three transfrmer paralleling using the circulating current methd are shwn in Figures 4-1 thrugh 4-3. Figure 4-1 is a schematic f the current circuit nly; redrawn frm the Paralleling Scheme figures t allw easier tracing f the lad current (I L ) and circulating current (I p ) paths. A current, prprtinal t the transfrmer secndary current, is fed t the M-0115A unit. Because f the secndary parallel cnnectin, hwever, this is actually the vectr sum f the desired lad current and any undesired circulating current. The M-0115A separates these currents, and sends them t the prper lad (LDC) and circulating current inputs f the assciated cntrl. Tw current lps are frmed. One invlves the K3 auxiliary transfrmers in each f the M-0115A units. This lp frms a measure f the transfrmer bank circulating current, subtracted frm the LDC cntrl input and frced t flw int the cntrl circulating current input. The secnd lp invlves the K1 and K2 auxiliary transfrmers. They frce the lad current t divide prperly between the varius cntrls s that each senses its prper prtin f the ttal bank lad. Thus, the LDC setting fr each cntrl may prperly be the same, regardless f whether r nt the assciated transfrmer is being used in parallel. The first current path shwn (Circulating Current) has a current analgus in angle and magnitude t the reactive current circulating thrugh the paralleled transfrmers. It als includes the M-0127A Overcurrent Relay, which is used t detect excessive circulating current and blck the tapchanger mvement, if this ccurs. Als, a lamp will alert the peratr when excessive circulating current is detected. The secnd path shwn (Balance Current), cnnecting the K1 auxiliary C.T. f the M-0115A mdules tgether, has a balance current which frces the tw lad currents f transfrmers #1 and #2 t be identical. This means that any difference in currents must flw in the circulating current path. 4 10

58 Cnfiguratin 4 The third and furth path shwn (Half Current and LDC Current), cnnecting the K2 auxiliary C.T. f the M-0115A mdules tgether, ensures prper peratin f the Lad Drp Cmpensatr circuit if ne f the transfrmers is taken ut f service by pening its breaker. Fr instance, if transfrmer #2 is taken ut f service by pening breaker 52-2, then half f transfrmer #1's lad current is frced t flw thrugh the half current lp. In this way, transfrmer #1's vltage regulating cntrl sees the same lad current as it did befre, and the prper amunt f line drp cmpensatin in the transfrmer #1 cntrl is maintained. This circuit cnfiguratin and grunding pints must be maintained, if transfrmers are t be successfully paralleled. A mre detailed descriptin f the thery f peratin is available frm Beckwith Electric upn request. Applicatin Nte #11, Intrductin t Paralleling f LTC Transfrmers by the Circulating Current Methd and Applicatin Nte #13, Advanced Paralleling f LTC Transfrmers by the Circulating Current Methd prvide a thrugh analysis f parallel LTC transfrmers perating by the circulating current methd. It is suggested that either the nn-sequential r Intertap time delay be used when paralleling. 4 11

The acceptable vltage range fr prper cntrl peratin is frm V ac. Pwer cnsumptin is less than 8 VA. The input vltage is referenced t line neutral (Pin 3). Cntrl users may encunter situatins where actuating the Drag Hands Reset pushbuttn n ne f any f ur adapter panels results in the lss f Vltage Sense fuse. The Drag Hands reset slenid is pwered frm the circuit tha pwers the ctnrl, and prvides the cntrl with sensing vltage. Initially, a 1/4 ampere fuse was used in this circuit, and mst recently a 1 ampere fuse was substituted t prevent further lss f the fuse. This phenmenn is due t the fact that as slenids age, then may becme sticky due t mechanical misalignment, hardened grease, r shrtened windings. The adapter panels include a 1 ampere fuse in the vltage sense circuit. This value shuld be adequate fr all but the mst extreme prblems. When a Drag Hands Reset Slenid that cnsistently blws a 1 ampere fuse is encuntered, it is recmmended that the custmer either remve the slenid fr cleaning and adjustment, r replace it cmpletely.

When using the Delta VAR2 paralleling methd, this input becmes the disable input fr Delta VAR2. This is used t keep the paralleled devices frm running t their limits (max raise r lwer) if they have been unparalleled fr maintenance, etc. Pin 16 Tapchanger Lwer Output This switched utput cnnects the tapchanger lwer winding t the surce f mtr pwer. When the cntrl calls fr a lwer, it is capable f switching up t 6 A at 120/240 V ac. Pin 17 Input 2 - Nn-Sequential Operatin/ Aut Tapchange Inhibit/Blck SCADA Nn-sequential Operatin When the Input Selectin (2) screen (in the Cnfiguratin menu) is set t NONSEQ INPUT, nn-sequential peratin is invked by mmentarily cnnecting this input t the nminal +12 V dc wetting surce (Pin 10) thrugh an external Frm a dry cntact. When this functin is enabled, the tapchanger cntrl times ut with the Time Delay setting between every tapchange. Aut Tapchange Inhibit When the Input Selectin (2) screen (in the Cnfiguratin menu) is set t NONSEQ INPUT, aut tapchange inhibit is invked by clsing and maintaining a Frm a dry cntact cnnected t this input and t the nminal +12 V dc wetting surce (Pin 10). As lng as this cntact is clsed, the tapchanger will nt time ut, thereby prhibiting raise and lwer cmmands. SCADA Blck Input When the Input Selectin (2) screen (in the Cnfiguratin menu) is set t SCADA BLK INPUT, all writes using SCADA will be blcked when the nn-sequential input is present.
