GIS High Voltage AC Withstand Voltage and Partial Discharge Test Equipment, Variable Frequency Series Resonant Test System for GIS GIL and Switchgear

The GIS High Voltage AC Withstand Voltage and Partial Discharge Test Equipment is designed for high-capacitance GIS and GIL testing applications.

The system uses variable-frequency AC resonant technology to generate high-voltage AC output for testing large-capacitance electrical equipment.

Variable-frequency AC resonant systems are widely used for GIS because they can provide high-voltage AC testing with reduced power requirements compared with conventional direct high-power test transformers.

“Our GIS has a large capacitance. Can your system test it?”

The required resonant system should be designed according to GIS capacitance, test voltage, test duration and frequency range.

“Our site power supply is limited.”

Variable-frequency series resonance can help reduce the required input power for capacitive test objects.

“We need a mobile system.”

The system can be designed for transportation and on-site commissioning.
