The short-circuit current sensor and the ground current sensor are respectively connected with the panel instrument main body through the optical fiber. After the failure. the sensor
transmits the signal to the panel mainframe host through the optical fiber to judge.
• Installed at the first substation outlet of the long line of the cable): it can be judged that there is a fault in the station or outside the line;
• Installed in the user into the transformer into high-voltage line: to determine whether the failure caused by the client;
• Installed in the overhead line and cable connection: to distinguish whether the fault occurred in the cable side;
• Installed on the outlet side of high-voltage switchgear or ring main unit: can judge the outlet fault branch.
1、for the failure of the line during troubleshooting troubleshooting to provide help and convenience.
2、according to the size of line load and line distribution of the situation, the rational development of fault indicator installatior、location.
3、the line normal operation. the indicator is in the reset state. without any indication.
4、when the line release short-circuit or ground fault, the line fault repair personnel according to the indicator flash status to troubleshoot areas where the fault
5, the product reset time Factory default time is 12h （reset time can be adjusted according to customer needs).
6、the product troubleshooting for the line to provide a powerful help, easy to find fault location;
7、to shorten the power outage time, and further improve the power supply;
8、product installation without power outages, free professional installation tools, demolition convenience.
