HV Capacitor Bank

SGCB series automatic high-voltage capacitor banks are divided into two main types:

 

Transformer test capacitor bank

Composed of shunt capacitors, pneumatic disconnectors, pneumatic earthing switches, current transformers, connecting busbars, post insulators, and a computerized central control system. It provides adjustable capacitive reactive current at different voltages and capacities to compensate inductive reactive current during transformer and shunt reactor load tests, so the test supply outputs mainly active current.

 

Synthetic circuit test capacitor bank

Composed of a main capacitor tower, a TRV frequency-tuning capacitor tower, and an arc-extension circuit capacitor tower. It is the core energy storage equipment for synthetic tests of high-voltage circuit breakers, GIS, and other switchgear. It supplies pre-charge injection voltage and generates the required transient recovery voltage (TRV).
