※ purpose

　　The frequency modulation series resonance test device is mainly used for AC withstand voltage test and partial discharge test of SF6 circuit breaker, GIS combiner, capacitive transformer, converter transformer, power cable and other high-capacity power equipment with voltage level of 1000kV and below.

　　It can be used as power frequency test equipment with appropriate tuning capacitor to make it resonate at the specified frequency.

　　※ performance and characteristics

　　1. Small volume and light weight;

　　2. High Q value;

　　3. The power input capacity is only 1 / Q of the output capacity; 4. Small amount of partial discharge;

　　5. There is no transient overvoltage after flashover of the test object.
