TBBS substation type auto-switched high-voltage shunt capacitor installation is usually installed besides 10kV or 6kV system of the substation. The equipment can effectively increase the power factor, reduce circuit losses, improve voltage quality and compensate reactive power.

The equipment is divided to several capacitor banks, according to the load of system, with auto-switching of SF6 switch & controlling of micro-controller, we can realize auto compensating of the reactive power. Meanwhile, some protection, such as open-delta unbalance voltage, single capacitor error, short circuit, over current, over voltage, under voltage etc, are set up to make system stable and reliable.

1. Rated voltage: 6KV or 10kv;
2. Rated frequency: 50Hz;
3. Equipment capacitance (max): 20000kvar;
4. Single bank capacitance (max): 3000kvar;
5. Rated reactance ratio: selected from 0.1%~1%, 4.5%~6%, 12%~13%.
