Introduction
 
The T-990 power cable fault locator is mainly used to locate the breakage, short circuit, and ground leakage faults of high
and low voltage buried power cables within 10KV (the insulation resistance to ground is less than 0.5 megohms) and the
depth of buried cables. Detection of the path direction.
It is suitable for street lamp cable maintenance, farmland irrigated ground cable fault investigation and repair, residential
property and landscaping belt buried armored iron sheet power cable, field power cable, highway, factory and mining enterprises,
iron tower communication base station direct-buried power supply cable fault investigation and other industries.
Three-channel design:
1Length test: It can directly test the length of the cable disconnection and short-circuit fault distance in the power-off state.
2 Anti-interference channel: adopts high-performance filter anti-power frequency interference circuit, and cooperates with the
signal generator to locate directly in the power-off state The location of the buried cable's leakage current to the ground,
and the direction and depth of the buried cable's path.
3 Full-band channel: Use a probe to test the location of the minor leakage fault of the directly buried low-voltage cable to
the ground under the power state. It is a powerful tool to shorten the troubleshooting time, improve work efficiency,
and reduce the labor intensity of line maintenance personnel.
