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.
Q: Why choose a series resonant system?
A: It can be particularly advantageous for high-capacitance equipment because resonance can reduce the required power supply capacity.
Q: What equipment is commonly tested?
A: Typical applications include XLPE cables, transformers, generators, GIS and other high-voltage equipment.
