Overhead Line Fault Passage Indicator

HESI Fault Indicator is installed on the overhead lines. 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.

Features of the Fault Indicator
Quick in finding the fault: By addressing the fault line and fault range quickly, the fault can be found quickly so that to reduce the fault shooting time.
Fault indicating and reset: Can issue the faults through alarming quickly when short-circuit or earth faults happen, and then reset according to the given method and setting time.

Low power: Using the low power design to assure the long lifetime of the products.
High reliability and wide applicability: Using the advanced adaptive technology design, the products can tuning the value of the fault current automatically according to the load current, so that the fault detection is highly reliable, stable, accurate and wide applicability.

Lithium Battery: Using the imported Lithium battery, no need of the external power supply, and the power quality is stable and reliable.
High anti-interference capability: Using the advanced industrial chip and processing technology, the hardware part of the products has high anti-interference capability.

Simple structure: Cast resin, sealed.
Easy installation: Both installation and disassembly can be done with special tools under power on state, no need to turn off the power supply.
