Cable Fault Location Bridge LB15
 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 fault generally 1~2MΩ,some even 10s MΩ or 100s MΩ, and called super-high resistance fault. When these faults occur, conventional methods like impulse method, second impulse method or arc reflection method, cannot locate the fault effectively because of the waveform cannot be sampled. LB15 uses Wheatstone  Bridge principle design to solve these super-high resistance faults effectively. It’s the necessary instrument of cable maintenance department.
