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 60kg which can be moved by two people or not more than 30kg moved by one people.

The system is comprised of frequency power, exciting transformer, reactors and voltage divider. Reactors are dry resin casted type, suitable for different cable tests.


Main parameters

Output frequency: 20~300Hz

Resonance voltage wave: sine wave, aberration rate is less than 1%

Full-load working duration: continuous 60 minutes

System quality factor: more than 20 under max. load

Frequency adjustment fineness: 0.1Hz, instability less than 0.01%

Power source: 220V or 380V normal electric supply
