Discharge coil for Phase advanced capacitors
 |
For safety operation of Phase advanced capacitor |
▲Discharge coil |
- Electric charge remains in capacitor after disconnecting capacitor from capacitor circuit.
- In this state ,it is dangerous to reconnect capacitor to the circuit or to practice inspection or maintenance.
- With discharge coil connected to capacitor circuit,residual charge can be consumed instantly.
- We recommend you install Discharge coil in capacitor circuit for safety operation.
▲Connection example
To avoid excess voltage caused by serial reactor ,please be sure to connect discharge coil to supply side terminal of serial reactor. |
