Cable Hipot Test System
Cable Hipot Test System
Description
Variable-frequency resonance voltage raising device makes reactor and capacitor achieve resonance by adjusting frequency of power, and then obtain high voltage and big current on the test objects.
This variable-frequency series-resonant voltage withstand test equipment is portable type, special for test cables. Weight of single part is not more than
The system is comprised of frequency power, exciting transformer, reactors and voltage divider. Reactors are dry resin casted type, suitable for different cable tests.
