UHV-75kVA/75kV AC Resonant Test System

The UHV-75kVA/75kV Series Resonant System is suitable for the handover and preventive testing of large-capacity, high-voltage capacitive test objects. The device features multiple protection functions such as overvoltage, overcurrent, zero-start, and system detuning (flashover). With its lightweight and portable design, it is highly convenient for on-site application, and incorporates DSP platform technology for enhanced control and performance.
