Mainly used to test various main insulation faults of 0-500kV power cables. It generates periodic high-voltage impulses to make the cable fault point break down and discharge, and work with TDR wave reflector and pin-pointer to measure the distance and locate the fault. With high-precision and high-stability electronic components and special structures and processes. It integrates voltage booster, rectifier, pulse capacitance and discharge control in one. Lightweight, portable, accurate and reliable, helping to quickly locate faults and shorten power outage time.
