Series Resonant Test System Variable Frequency AC Resonance Hipot Test Equipment for Cable, GIS, Transformer, Generator and High Voltage Electrical Equipment

The Series Resonant Test System is a professional high-voltage AC testing solution designed for withstand voltage and dielectric testing of high-capacitance electrical equipment.

Using the principle of series resonance, the system combines a variable frequency power source, excitation transformer, high-voltage reactors and voltage measurement equipment to form a resonant circuit with the test object.

By automatically adjusting the output frequency, the system can reach the resonance condition and generate the required high AC test voltage with relatively low input power.

It is widely used for high-voltage power cables, GIS, transformers, generators, motors, busbars and other capacitive electrical equipment.
