TROUBLESHOOTING 1. After power turned on, the controller shows capacitive state, Capacitor is not switched on . A. The wiring is not correct. Please check the voltage and current phases sequence (refer to wiring diagram). B. If other capacity compensation devise is running on the load side, it may make the load real capacitive circuit. 2. After a capacitor switched on, the Power Factor remain unchanged. The current transformer may not in the right position. The current go through capacitors should also go through the CT. (refer to wiring diagram). 3. After capacitor switched on, Power Factor decrease. A. The wiring is not correct. Please check the voltage and current phases sequence (refer to wiring diagram). B. Turn off all power to the capacitor cabinet, then turn on power again (reset the system). 4. The controller can not follow the change of the load fast enough. The load changes too fast, such as welding machine, derrick and crane etc. Use dynamic power factor control system in these cases. 5. After capacitor switched on, the current go through capacitors raises too high. The circuit may have high harmonic current and/or harmonic voltage. 1. Add an inductor in each capacitor, it protects the harmonic current go through the capacitor, but can not eliminate the harmonic current of network. 2. Install harmonic current filter. If harmonic current is too big, installing a harmonic current filter is an effective way to limit the harmonic current.
