Introduction
To accurately identify power cable fault points, the cable fault
location instrument employs 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.
Features
1. 5-inch touch-high brightness LCD ensures visibility under
sunlight.
2. Adopt acoustic and magnetic synchronous positioning technology
to automatically calculate the acoustic and magnetic time
difference.
3. It has background noise reduction technology and can choose from
a variety of filtering methods. It has path deviation indication.
4. Equipped with multi-layer physical isolation signal sensors,
waterproof grade IP65. Built-in large-capacity lithium battery,
long standby time, equipped with fast charger.
5. Small and lightweight, easy to operate, and simple human-machine
interface.
