China Power Substation AC Voltage WithstTest Variable Frequency Resonant Test Systems

Brief introduction
BPXZ-HT makes the reactor and tested capacitor in resonant by adjusting the frequency of the power source, to get high voltage and heavy current from measured equipment. Now it is a new method and trend for high voltage test and widely used.
BPXZ-HT uses special SPWM digital wave-generate chip, resolution is 16 bits, the frequency adjustment fineness could be 0.1Hz if the frequency was 20~300Hz; adopts sine asynchronous fixed wave carrier modulation, to ensure the waveform output is good in the whole frequency range; adopts advanced IPM module, ensure the stability and safety of the device under minimum weight.
Products features

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
