LB460 Intelligent Digital Cable Fault location Bridge

Introduction

On the cable fault testing, there are always faults like intermediate joint damp of insulation, water-in cable, the fault cannot be burn through by flashover. These faults generally 1~2MΩ,some even 10s MΩ or 100s MΩ, called super-high resistance fault. When these fault occur, the methods based on impulse reflection principle cannot locate the fault effectively. Intelligent digital cable fault location bridge LB4/60, uses mew digital location model, and combines with Wheatstone Bridge tech and constant current burn through technology, the output voltage up to 60kV, location current 600mA, having solved these super-high resistance faults effectively. It’s the necessary instrument of cable maintenance department.
