3kV-66kV Overhead line Fault circuit Indicator and fault passage indicator for indicating earth fault and short-circuit fault

Specifications

Senses short circuits and earth fault by bright LEDs and Red Disc.

Description

Fault indicator is installed on the over-head lines, power cables and the busbars of the switch cabinet to indicate the fault current path. When line fault comes, the line inspector can determine the fault section, fault branch and fault point quickly by the alarm display on the indicator. It changes completely the methods of blind line inspection and finding the fault area through switching on one area after another in the past. Thus, it reduces the area and time of power outage and improves the reliability of the power supply.
