LB4/60A Intelligent Digital Cable Fault Location Bridge

Introduction

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