4 Switchboard Instruments WMN type WMN type wide-angle indicating switchboard instruments Description WNN-type meters are used in many industrial applications such as switchboards, supervisory panels, metal-clad switchgear and control desks. These are compact in size and easy to read. Scales have equal intervals and indicate through a 40 angle, a feature which distinguishes them from the conventional meters. Meters can be read at a distance, since instrument surfaces are protected by a non-reflecting glass and are not affected by reflections from room lighting. Ammeters are provided with an overload scale in red. These instruments comply with the requirements of JIS C0 and are highly reliable. They can withstand a great deal of abuse in use because of their rugged construction. Features High accuracy External magnetic fields cannot influence readings. Accuracy class:. Easy-to-read long-scales and pointerindications can easily be read from a distance. 0 0mm and 0 0mm front frame sizes. Auxiliary equipment such as shunt, impedance box and series resistor is available. 0mm square 0mm square Meter Description 0mm square Type AC ammeter For direct connection Measuring range Extended range type (0X3X) 0 A 0 3A 0 3A 0 3 9A 0 A 0 A 0 0A A 0 A 0 4A 0 0A 0 0 0A 0 30A Operating principle RMS responding Moving iron Power consumption 0.4VA 3VA WMNAR3 (RMS responding) WMNAS3 (Moving iron) 0mm square Type WMNAR (RMS responding) WMNAS (Moving iron) For connection to CT CT ratio Measuring range /A 0 A 0/A 0 0A /A 0 A 0/A 0 0A 30/A 0 30A 40/A 0 40A 0/A 0 0A 0/A 0 0A 7/A 0 7A 00/A 0 00A 0/A 0 0A 00/A 0 00A 300/A 0 300A 400/A 0 400A 00/A 0 00A 00/A 0 00A 70/A 0 70A 00/A 0 00A 000/A 0 000A 000/A 0 ka Extended type (0X3X) 0 A A 0 4A 0 0 0A A A 0 0 0A 0 0 0A 0 7 A A A A A A A A A A A 0 ka 3kA Operating principle RMS responding Moving iron Power consumption 0.4VA 3VA 09 Ordering information Specify the following:.

89 Power Factor Controllers Automatic power factor regulators QC0E and QCE Automatic power factor regulator QC0E, QCE Description Automatic power factor regulator (APFR) is a device which is designed to maintain the target power factor by regulating lagging or leading current. The APFR is designed to monitor the reactive power within the circuit continuously and to provide ON/OFF signals automatically to control circuit breakers in a capacitor bank. In an electrical network such as an industrial plant using induction motors which produce reactive power, the power factor will drop. This will cause a power loss, a line voltage drop and other disadvantages. In conventional electrical systems the efficiency of transmission and distribution equipment is improved by installing fixed capacitors across the line. However, an over-compensation may arise when there is a light load, such as at night, which would result in an increase in line voltage and excess current. The APFR supervises the power factor in the system, and controls the power factors by switching capacitors ON or OFF as the situation requires in the face of a reactive leading or lagging load. ow power loss Correcting the power factor with a power capacitor reduces the line current. This also reduces the power loss caused by the resistances of the power cables and transformer windings. Effective use of power receiving facility Correcting the power factor with a power capacitor reduces the line current. Since this produces margins in the transformer capacity and the current-carrying capacity of cables, a heavier load can be carried without adding more facilities. Stable supply voltage for long equipment service life A reactive power, especially a leading reactive power at a light load (at night), often produces an overvoltage and shortens the service life of lamps. Use an automatic power factor regulator to suppress a voltage decrease at a heavy load and a voltage increase at a light load. aborsaving unmanned operations This regulator outputs capacitor connection and disconnection commands automatically to maintain an optimum power factor. The simple setup for this output saves labor applied to power factor correction. Features Compact (DIN size) and lightweight The DIN-size compact unit permits easy mounting hole on the panel and enhances work efficiency. The -bank and -bank models have front panels of the same size (44mm 44mm). Since in the panel cutout hole sizes are also the same (3mm 3mm), it is possible to use panel cutout holes of one uniform size. QC0E 0V and 440V power supplies The regulator can be connected to a 0V or 440V power supply. Set the voltage input switch on the front panel to the control power supply voltage being used. Connect control power cables to the correct terminals of the terminal block in accordance with the control power supply voltage being used. Automatic setting of control level by microcomputer The mode and data are set simply by using four keys. The microcomputer automatically sets the levels at which capacitors should be connected or disconnected. Three types of capacitor connection and disconnection control by purpose. Cyclic control or optimum control (automatic selection) Under cyclic control, capacitors of the same capacitance are connected and disconnected in ascending order of capacitor number. Under optimum control to keep the number of connections and disconnections minimal, a capacitance change is calculated from the measured reactive power and the target power factor and a capacitor of the nearest capacitance is connected or disconnected. Either control is selected in accordance with the set capacitor capacitance.. Unconditional cyclic control Capacitors are controlled cyclically, irrespective of their capacitances. 3. Multistep control Capacitors having capacitances incremented in multiples of two (e.g. ::::::, ::4:4:4:4, and ::4:::) are simultaneously connected or disconnected to optimize the capacitance with a minimal number of steps. 09/

90 Power Factor Controllers Automatic power factor regulators QC0E and QCE Useful functions. Polarity error diagnosis function If a polarity error in wiring is detected, the regulator lights the alarm lamp and sounds the buzzer to indicate the miswiring.. Forced disconnection function To protect capacitors from being damaged or reactors from being burnt by excessive harmonics, or to disconnect capacitors unconditionally at night, external time switch signals can be input to the regulator. The signals automatically disconnect the connected capacitors in proper order. Automatic capacitor disconnection at light load When the load of a power line decreases at night, the connected capacitors may increase the leading reactive power and cause an overvoltage. A voltage increase on the power receiving side will shorten the service life of lamps and other load equipment. To prevent an excessive leading power factor at a light load, the regulator automatically disconnects capacitors.

94 Power Factor Controllers Automatic power factor regulators QC0E and QCE Operation of automatic power factor regulator Cyclic control Under cyclic control/optimum control, the regulator connects and disconnects capacitors of the same capacitance cyclically. Under unconditional cyclic control, the regulator connects and disconnects capacitors of different capacitances cyclically, irrespective of the set capacitance.. Capacitor connection When the reactive power exceeds the level at which more capacitors should be connected, the red lag lamp lights. If the red lamp remains lit for the set delay time or longer, the corresponding capacitor control output goes ON and the red lamp for the capacitor bank lights. When the reactive power of the circuit is still over the connection control level and the red lag lamp remains lit, the capacitor control output for the next capacitor goes ON after the delay time. The capacitor control outputs go ON one by one at the delay time intervals until the reactive power level of the circuit falls within the allowable range.. Capacitor disconnection The red lead lamp lights when the circuit load decreases and the connected capacitors increase the leading reactive power of the circuit beyond the level at which a capacitor should be disconnected. When the red lead lamp remains lit for the set delay time or longer, the corresponding capacitor control output goes OFF and the red lamp for the capacitor bank goes OFF. The capacitors are disconnected in the order of their connection.

95 Power Factor Controllers Automatic power factor regulators QC0E and QCE Optimum control Under optimum control, the regulator connects or disconnects the capacitor with the capacitance closest to the change of reactive power among capacitors of different capacitances. If there are two or more capacitors of the same capacitance, the regulator connects or disconnects the capacitors cyclically for optimum control (the number of switchings) match.. Capacitor connection The red lag lamp lights when the reactive power level exceeds the level at which more capacitors should be connected. The regulator calculates the difference between the current reactive power and the level at which more capacitors should be connected, and integrates the calculated value for the set delay time. The average value per unit time is calculated from the integrated total and a capacitor having the capacitance closest to the average value is selected. The capacitor control output for the capacitor is turned ON and the red lamp of the capacitor bank lights. The regulator continues integrating and averaging the differences between the current reactive power level and the level at which more capacitors should be connected, and selecting optimum capacitors. The capacitor control output is turned ON repeatedly until the reactive power of the circuit falls within the allowable range. Figure shows an example of a capacitor connection control with a load variation pattern.. Capacitor disconnection When the circuit load decreases, the already-connected capacitors increase the leading reactive power level. If the reactive power level exceeds the level at which capacitors should be disconnected, the red lead lamp lights. The regulator calculates the difference between the current reactive power level and the level at which capacitors should be disconnected, and integrates the calculated value for the set delay time. The average value per unit time is calculated from the integrated total and a capacitor having the capacitance closest to the average value is selected.

The power factor at a light load can be controlled in the same way.. Capacitor connection When the reactive power level exceeds the level at which more capacitors should be connected, the red lag lamp lights. If the red lamp remains lit for the set delay time or longer, the capacitor control outputs for the next step go ON or OFF and the red lamps of the capacitors light or go OFF. If the reactive power level of the circuit is still over the level at which more capacitors should be connected and the red lag lamp remains lit, the capacitor control outputs for the next capacitor go ON or OFF after the set delay time. The capacitor control output is turned ON or OFF sequentially at the delay time intervals until the reactive power level of the circuit falls within the allowable range.. Capacitor disconnection The red lead lamp lights when the load decreases and the connected capacitors increase the leading reactive power level of the circuit beyond the level at which capacitors should be disconnected. When the red lamp remains lit for the set delay time or longer, the capacitor control outputs for the next step go OFF or ON and the red lamps of the capacitor banks go OFF or light.

If 00% is set as the target power factor of mode symbol F, a control of leading reactive power is performed. 4. Set the minimum load value to one slightly higher than the actual minimum load of the equipment to ensure an accurate light-load disconnection even when the measuring error or circuit constant fluctuates slightly. Example: When the actual minimum load of the equipment is 00kW, set the value to 0 k W (00.). Note: Select a delay time suitable for the capacitor discharger. When using a discharging resistor, set the delay time to 300s (min) or 00s (0min). An inappropriate delay time may damage capacitors or reduce their service lives /99

103 Power Factor Controllers Automatic power factor regulators QC0E and QCE Calculating CT ratios CT ratio Example: When the primary current is 400A and secondary current is A. 400 = 0 CT ratio = 0 Determining capacitances and number of capacitor banks to improve the power factor by switching-on capacitors The capacitances and the number of capacitor banks are determined as follows: For capacitors having the same capacitances When load variation (increase and decrease of load) is frequent.. Determining the target power factor Consider how far the power factor can be improved from the current value by automatic control. Example Current power factor (before improvement): 0. Target power factor (after improvement): 0.9 Maximum demand power: 000kW θ: Favtor: θ P: Active power S (kva) Q: Reactive power S: Max. demand power COSθ: Target power factor COSθ0: Improve the power factor P (kw)=000kw θ COSθ Q (kvar) Q=00kvar COSθ=0.9 Cm=40kvar COSθ0=0.0. Calculating the capacitances needed to improve the power factor See the capacitor selection chart (Page 09/0) to calculate the necessary capacitance. Example To improve the power factor from 0. to 0.9, t h e f a c t o r K should be 0.4. Therefore, the necessary capacitance (Cm) is obtained as follows: Cm = Maximum demand power K = 000kW 0.4 = 40kvar The necessary capacitance is 40kvar. 3. Calculating the target reactive power Calculate the target reactive power from the target power factor (after improvement) and the maximum demand power. Example The target value is calculated using t h e f a c t o r K selection table. (Page 09/0) Target power factor: 0.9 K=0. The target reactive power (Q): Q =Maximum demand power K =000kW 0. =00kvar () If n, the number of banks should be six. () If n <, the number of banks should be n. (Round up any fraction) In this example, n = 40kvar =.7 < 00kvar If the fraction is rounded up, the number of necessary banks is 3. Note: The necessary capacitance for power factor improvement (Cm) means the total capacitance to be controlled by this unit.. Calculating the capacitance per capacitor bank If each bank should have the same capacitance, the capacitance needed to improve the power factor must be divided by the number of banks calculated at step 4. Example Capacitance per capacitor bank: Capacitance needed to improve the power factor (Cm) Co = Number of capacitor banks (n) In this example, Co = Cm = 40kvar = 0kvar n 3 (banks) Since there are no 0kvar capacitors, a 00kvar-capacitor can be used. For capacitors having unequal-capacitances When load variation is a slight and stable all the year round. Target power factor and the necessary capacitance for power factor improvement are calculated using step and. Current power factor (before improvement): 0. Target power factor (after inprovement): 0.9 Necessary capacitance for power factor improvement (Cm): 40kvar For load variation as shown below, calculate the reactive power variation using K. Example When P is 0kW, Q = P K = = kvar Capacitor C = 00kvar When P is 400kW, Q = kvar Capacitor C = Q C = kvar, C = 0kvar When P3 is 00kW, Q3 = 34kvar Capacitor C3 = Q3 (C C) = 74kvar, C3 = 00kvar When P4 is 000kW, Q4 = 40kvar Capacitor C4 = Q4 (C C C3) = 90kvar, C4 = 00kvar (kw) 00 P4 4.

Inputs of "a: the answer back signal of CB ON" and "the monitoring of TC coil" are used exclusively. Device error output is a normally closed contact (normally excited, and if an error occurs, excitation terminates and contact opens). Therefore, a time delay of about 00ms occurs before the contact opens, since the power has been on (in operation). Consider the use of a timer, if necessary, if you create an external sequence. If you have to connect a heavy load exceeding relay s contact rating, be sure to use it in combination with FUJI s miniature power relay HH. See page 09/3 Input/output specifications.
