Ground fault indicator High voltage switchgear short circuit indicator

The panel-type short-circuit ground fault indicator is installed in the ring main switch, cable branch box and transformer box in the distribution network system. A real-time monitoring device for indicating a single-phase short-circuit-to-earth fault in the corresponding cable segment. If the line fails, the staff can use the indicator light to give an alarm indication, quickly determine the fault section, and find out the fault point. At the same time, the alarm fine can be sent to the monitoring center server in real time. Display the fault area and specific location on the monitoring computer screen, guide

The patrol personnel quickly determined the fault section and identified the fault point. These indicators provide the best way to resolve troubleshooting issues. It is of great significance to improve work efficiency, shorten power outage time, quickly restore power supply, improve power supply reliability and economic benefits.
