Mode: HFRS serial
Variable frequency.
Voltage: 200kV - 2000kV
The variable frequency resonant system is designed for 1000kV and below voltage SF6 circuit breaker, GIS, XLPE power cable and other high capacitance power equipment on-site withstand test and 1000kv and below voltage instrument transformer, coupling capacitor, zinc oxide power equipments partial discharge test.

MAIN FEATURE
- High Q value
- Wide variable frequency range: 30-300Hz
- Low partial discharge (PD) level
- Can do on-site test for 10km length 200kV XLPE power cable (1200 mm2)
