AC withstand voltage testing for cables, GIS, transformers & generators
Our variable-frequency series resonant test systems apply AC withstand voltage tests to XLPE/PILC cables, GIS, SF6 switchgear, power transformers and large rotating machines. By tuning the reactor to the test object capacitance, only a small input power is needed — making high-voltage testing safe, portable and energy efficient.
Real models from our current catalogue. Voltage, current and functions can be customised to your test object — send us your specification.
