Remote Overhead line  Fault Circuit Indicator for Smart Grid

^Description

Overhead power line fault indicator with Three color light display suitable for overhead lines with a 50KV below four remotes short circuit &Earth fault indicator, through measuring the current of a cable, to judge the fault on the power lines according to the change of current, grounding fault, and the fault state, real time current, battery voltage and other information is uploaded to the remote server, which provides reliable data for the various types of fault diagnosis and location of overhead lines

Function display

Flag state

1) Normally, Flag is on blanket position. Every 3hour, Flag will reset one times for avoiding un fault turn to red flag.

2) When short circuit fault happen, it will turn to red flag state; After reach reset time or when the line current restore, Fault indicator will turn back to blanket state;

3) when the earth fault happen, it will turn to red flag state. It will be automatically turn back blanket state when line power off and current restore, or wait until reach reset time.

Fault indicating Led light：

1) short circuit permanent fault indicating: Six 3-color led will shine red color, and four times, every 2 second，And turn to red flag at same time。

2) short circuit temporary fault indicating: Six 3-color led will shine green color, and four times, every 2 second，And turn to red flag at same time。

3) Earth Fault indicating：Six 3-color led will shine Blue color, and four times, every 2 second. And turn to red flag at same time.
