Introduction
To accurately locate power cable fault points, the cable fault
location instrument uses the acoustic and magnetic synchronization
method. The electronic flashover, generated by the impact discharge
generator, is detected and amplified by a specialized probe. The
precise location of the fault is determined through auditory and
visual judgment. This device completes the precise positioning of
cable faults within a rough measurement range and collects the time
difference between acoustic and magnetic signals. It integrates
advanced positioning technology with path-assisted testing,
offering multiple test modes and a variety of informative prompts
to efficiently and accurately locate cable faults.
