Specifications

overhead type fault indicator transmission distribution system
Overhead type  fault  indicator transmission distribution system
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;       

*ultra low power real-time sampling;

* When line current value5A,CT can supply meet the indicator power requirement

*Sampling accuracy:  I<10A1%,I>10A2%

* Sensor factory automatic calibration, to ensure consistency;

*intelligent motor control flop;

*Support remote, telemetry, remote control, remote adjust;

*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

 

Part of test character:

Function display

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
