20–300 Hz Series Resonant Test System with 108kV Voltage Level and Modular Structure for AC Resonant Test System

Our Series Resonant Test System is designed for AC withstand voltage testing of high-voltage electrical equipment. Using the series resonance principle, the system combines a variable-frequency power supply, excitation transformer, high-voltage reactor and capacitive voltage divider to generate the required AC test voltage.

The system can be configured for different voltage levels, load capacitances and testing requirements. It is suitable for electrical testing manufacturers, power utilities, commissioning contractors, transformer factories and high-voltage testing laboratories.

• AC withstand voltage testing of high-voltage insulation systems

• Resonant frequency tuning according to the test load

• Test voltage monitoring and regulation

• Overvoltage and overcurrent protection, subject to configuration

• Test data recording and reporting, where supported

Power cables, power transformers, GIS, switchgear, generators and other electrical equipment requiring AC dielectric testing.

Before purchasing, confirm the required test voltage, rated capacity, load capacitance, frequency range, input power supply, reactor configuration and applicable testing standards.

It can be configured for cables, transformers, GIS, generators and other suitable electrical test objects, depending on the system ratings.

Yes, a manufacturer can design a configuration based on the customer's test voltage, load capacitance, capacity and application requirements.

Please provide the equipment under test, rated voltage, required AC test voltage, test duration, load capacitance or cable length, local power supply and applicable standard.
