Product details

Product Introduction

The Power Frequency Resonant System is mainly used for ac withstand voltage test of cross-linked cable, hydraulic generator, main transformer, bus, GIS, etc. It has a wide range of application and is an ideal withstand voltage equipment for local, municipal and count-level high voltage test departments and electric power installation and repair and test engineering units.

The device is mainly composed of frequency conversion control power supply, excitation transformer, reactor, capacitor voltage divider and compensation capacitor (optional).

Product nickname: series resonance, frequency conversion resonance, frequency conversion series resonance, series resonance test equipment, series resonance voltage withstand device, cable voltage withstand series resonance device
