RSXZ-L-I Ac Variable Frequency Resonance Series Cable Withstand Voltage Test Device
Product Features
1. The device with large output capacity and small power capacity, low cost, easy to operate and safe.
2. Serial resonant system actually is current filter circuit, make the current which through it be fundamental current, the output voltage distortion (THD) is very small, and better than all the AC voltage withstand equipment.
3. The short circuit current after flashover or breakdown is only less than 1/10 (1/Q) of the measured current, can effectively prevent the damage to fault point after breakdown.
4. Auto blowout the arc after flashover, it is a long and stable process to recover the serial resonant voltage, safe.
