Capacitance compensation cabinet

The capacitor cabinet refers to closing the knife fuse switch and circuit breaker, and the reactive power compensation controller outputs a control signal according to the phase difference between the voltage and current of the incoming cabinet to control the closing and opening of the AC contactor, thereby controlling the input and withdrawal of the capacitor.

The function: 

1. Improve the power factor of the power supply, compensate for the reactive power, and reduce the inductive load; 

2. Stabilize the grid system voltage during a short circuit ;

3. Improve the system grid voltage ;

4. To act as a filter .

Whether the capacitor cabinet is working normally can be judged by the reading of the power factor meter. 

If the reading of the power factor meter is around 0.9, it can be regarded as working normally.
