On-site detection, diagnosis and fault location system for partial discharge of high-voltage cables

It is used for on-site frequency conversion resonance voltage test of 10kV~220kV high-voltage cables, on-site partial discharge detection and fault location under oscillating waves. It can conduct AC withstand voltage and partial discharge fault location tests on high-voltage cables with a length of 0.2km-8km.
