XZB-D portable cable withstand voltage tester adopts the method that adjust the frequency of power supply, making reactor and tested capacitor get resonance and the HV high current is available from tested equipment. This is a new method and trend at present, widely applied at home and abroad. The tester equipment is composed of variable frequency power supply, excitation transformer, reactor and capacitor. The capacitor and reactor of tested equipment constitute the form of series resonant connection. Voltage divider is in parallel in tested equipment, which used to test the resonant voltage of it and as over-voltage protective signal. The frequency power output through excitation transformer is coupled to series resonant circuit, providing excitation power of series resonance.

1.Small in volume, light in weight.

2.This system need one person to carry the device less than 30KG, two people less than 60KG. Suitable to carry on site.

3.Power supply, Single phase: 220V or 380V, convenient to get power on site.

4.Reactor uses epoxy cast, beautiful and reliable, suit for all kinds of cables.

5.110kV and above voltage level cable withstand voltage test use oil-immersed reactors, when the weight of single machine is more than 100kg, optional dedicated small electric cranes
