Fault Passage Indicator for Grounding Network

Specifications

SUMMARY

      SNV308.1 series overhead type Fault Indicator system is based on the Sensor that through CT get the (6KV-50KV) line's current signal, through smart computer chip(IC) by program calculating, Analysis,judge the short circuit or ground fault. When Sensor detect the fault happen, then the Fault indicator warn the manager through turn red flag, and shine 3 color ultra-LED. It is good for power managing user to find the fault happen reason and place, then fast solve the problem and make the power restore.

     *SNV308.1 Fault Indicator with the aid of the remote control PDA(SNV306.1), User can read, reset the indicator's setting parameter, and can read the online real time current etc

     *SNV308.1  Fault Indicator with the aid of the professional control terminal equipment(SNV309.1) and Web server, it canAchieve to remote read and manage the Fault indicator state on times.

 Flag state

1) Normally, Flag is on blanket position. Every 3 hours, 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 reaching 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 piece 3-color LED will shine flash red color, and four times, every 2 second,and turn to red flag at same time.

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

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

Yellow state LED light:

Battery voltage too low:Shine 1 time, every2second

Battery voltage low: shine 2 time, evey2second

Wireless setting state:   shine 4 times, every 2 second
