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

The Variable Frequency Series Resonant AC Hipot Test System is designed for AC withstand voltage testing of high-capacitance electrical equipment.

Compared with conventional high-capacity power frequency test transformers, a series resonant system uses the resonance principle to reduce the required input power while producing the required high test voltage.

This makes the technology especially suitable for testing equipment such as long high-voltage cables, large transformers, GIS and generators. Current industry product pages commonly position variable-frequency series resonant systems for these high-capacitance applications.
