Mainly used for 1000KV and below voltage level SF6 circuit breaker;

Field AC voltage withstanding test of GIS combined electrical appliances and other large capacitance power equipment of power cable;

Small size, light weight, high Q value, small partial discharge.

There is no transient overvoltage after flashover.

The input capacity of the power supply is only 1/Q of the output capacity.

Inductance-modulated resonant reactor:

The resonant test device is mainly used for AC withstand voltage test of SF6 circuit breaker, GIS combination, XLPE power cable and other large capacity power equipment with voltage level of 1200 kV and below, and also for partial discharge test of transformer, coupling capacitor, zinc oxide arrester and other power equipment with voltage level of 500 kV and below.

Main technical features:

1. Small size, light weight and small power supply capacity;

2. Q value is high, most of Q value is more than 40;

3. The partial discharge of the system is low.

4. There is no transient overvoltage after flashover, and the use of the system is guaranteed by safety.
