Sepam 000 D. Advantages Complete protetion against internal transformer faults, Restrited earth fault protetion inluded, Proessing of transformer and neutral oil, Buhholz and thermostat data, Simple implementation due to the use of neural networks, v Simplified sizing of urrent sensors, v Few settings, v No mathing transformers required, Measurement: v Primary, seondary urrents and phase shifts, v Residual urrents, v Differential and through urrents, v Memorization of differential and through urrent at the time of the fault, Test position, Disturbane reording, High level of eletromagneti ompatibility (EMC) makes it possible to use digital tehnology in eletrial substations, without the need for any partiular preautions, Sepam 000's ontinuous self-testing sets the devie in a predetermined fail-safe position when failures our, preventing random operation, Terminal bloks whih may be individually disonneted while energized to failitate maintenane, Setting and testing are extremely simple: v the settings may be made on the front panel (serial link): - one by one, using the TSM00 poket terminal, or the SFT80 PC software program, - all at one using the SFT8 PC software program (downloading), The optional ommuniation funtions an be used for remote setting of protetions, remote metering, remote annuniation and remote ontrol via a two-wire link with a supervisor for entralized management, ISO 900 ertified design and manufaturing proesses.

4 Presentation (ont'd) The terms winding and winding are used like that : Definitions winding refers to the iruit that has the highest voltage Un; the orresponding urrents are onneted to onnetors A and B, winding refers to the iruit that has voltage Un' less than or equal to Un; the orresponding urrents are onneted to onnetors A and B. By extension, this definition also applies to an auto-transformer for whih windings are partially ombined but whih have different voltage levels. U, I winding U, I winding U', I' winding U', I' winding example : U= kv, U'= kv example : U=0 kv, U'= kv The zone proteted by Sepam 000 D is the zone between the urrent sensors onneted to onnetors A and B, at one end, and the sensors onneted to onnetors A and B at the other end.

5 Protetion Differential protetion ANSI ode 87 T funtion number F0 I I' 87T This protetion adjusts the urrent phase and module of eah winding aording to the parameterized transformer onnetion. It then ompares the adjusted urrents, phase by phase. It is ativated if the differene in urrents Id for at least one phase is greater than the operation set point. The set point is defined by the operation harateristi below. Protetion stability with respet to external faults is also ensured by the biased harateristi and by the nd and th harmonis neural network restraint whih analyzes the perentage as well as the differential and through urrents. This restraint prevents unwanted tripping when: the transformer is swithed on, an asymmetrial fault ours outside the zone, ausing saturation of the urrent transformers, the transformer is supplied by exessive voltage (overfluxing).

It offers the advantage of having greater sensitivity than differential protetion. > > > > The funtion is based on a omparison of the residual urrent Io (Io = I + I + I) and the neutral urrent Ineutral. It piks up if the module of the differene Io-Ineutral is greater than the operating set point. This set point is defined by, first, a minimum Iso set point and, seondly, by a perentage type tripping harateristi with a slope of.0 and an Ino restraint urrent harateristi in normal onditions (see urve). > > > Iro = I + I + I The sensitivity of the protetion is determined by the phase urrent sensors with a minimum Iso set point of % In. The proteted zone is between the phase CTs and the neutral CT. Stability with external faults When an external fault is deteted, the restraint urrent beomes equal to: > > > > * (I + I + I) + Io/ ; This makes the protetion insensitive to urrent transformer saturation without inhibiting its operation.

8 Disturbane reording Operation Used to reord analog signal and logial states. Reord storage is triggered by a triggering event: tripping of differential protetion, tripping of restrited earth fault protetion, loal manual triggering, remote manual triggering. The duration of the signal reorded before the triggering event may be set using the poket terminal via the osillography item in the status menu. The date of reord storage may also be aessed via the poket terminal in the osillography item of the status menu and via the ommuniation link (refer to Jbus/Modbus ommuniation doument). This date orresponds to the date of the triggering event. The stored event begins before the triggering event and ontinues afterwards. The reord inludes of the following informations: values sampled from the different signals, the date, the harateristis of the reorded hannels. The files are reorded in FIFO (First In First Out) type shift storage: the oldest reord is erased when a new reord is triggered. Priniple stored reord triggering event Charateristis reord duration the duration before the triggering event may be set from to 8 periods. reord ontent set-up file : date and hannel harateristis, data file : values per period/reorded signal analog signals reorded all urrents onneted to the aquisition boards logial states reorded tripping outputs O and O, differential and restrited earth fault operation digital inputs, I to I8 number of reords stored file format COMTRADE IEEE C IEC 0- time Transfer Files may be transferred loally or remotely: loally: using a PC whih is onneted to the onsole onnetor and has the SFT80 software pakage (version later than 980), remotely: using a software pakage speifi to the remote monitoring and ontrol system. Restitution Reord signals may be restituted using the SFT 8 software program. Display The signals are displayed from a reord by means of the SFT8 software pakage.
