Electric Power Overhead Line Current Fault Indicator 

SUMMARY

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

There are two channels for reading and managing the remote fault indicators. One is through GSM mobile phone SMS command control. Second is user computer software control. Power managing user, can get the fault indicator information on times

DESCRIPTION

SNV series indicators suitable for overhead lines network under a 50KV, for remotes short circuit &Earth fault indicator, through measuring the current of a conductor 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

Production Character:real-time sampling of current per cycle;       

50. ultra low power real-time sampling;
50. When line current value5A,CT can supply meet the indicator power requirement
50. Sampling accuracy:  I<10A±1%,I>10A±2%
50. Sensor factory automatic calibration, to ensure consistency;
50. intelligent motor control flop;
50. Support remote, telemetry, remote control, remote adjust;
50. There are two piece LI-iron battery inside. Battery life:8-10year

1) 3.2V,600mah lithium -iron rechargeable battery for working

2)3.6V,2700mah lithium -iron battery for back up

Battery life:8-10year 

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
