Cable fault tester

summary:

This tester is mainly used for locating broken wires, short circuits, and ground leakage faults (insulation resistance to ground within 0.5 megohms) of high and low voltage buried power cables within 10KV level (expandable to 50kV), as well as detecting the depth and path direction of buried cables.

Suitable for maintenance of streetlight cables, troubleshooting of cable faults in farmland irrigated land, underground armored iron sheet power cables in residential properties and garden green belts, field power cables, highways, factories and mines, direct buried power cables for tower communication base stations, and other industries.

This instrument adopts advanced integrated circuit technology, cutting-edge calculation methods, simple circuit structure, high reliability, and low misjudgment rate.

Three channel design:

1. Length testing: The distance of cable breakage and short circuit faults can be directly tested under power-off conditions.

2. Anti interference channel: High performance filtering and anti power frequency interference circuit is used. In the event of a power outage, a signal generator is used to locate the ground leakage position of the buried cable, and the path direction and depth of the buried cable are measured.

3. Full frequency channel: Use a probe to test the location of slight ground leakage faults in buried low-voltage cables when powered on. It is a powerful tool to shorten the time for fault diagnosis, improve work efficiency, and reduce the labor intensity of line maintenance personnel.
