what is fault indicator 

Description

SNV Indicators 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

Character:

l real-time sampling of current per cycle；       

l ultra low power real-time sampling；

* When line current value≧5A，CT can supply meet the indicator power requirement

*Sampling accuracy5-20A±1.5A，20-800A±3%

l Sensor factory automatic calibration, to ensure consistency；

l intelligent motor control flop；

l Support remote, telemetry, remote control, remote adjust；

Function character

a. real time measurement of three-phase on line current；

b. Detection and judgment of short circuit fault；

c. Detection and judgment of ground fault

d. Data Upload function；

e. Parameter setting

f. Support setting controller (PDA)

g. Intelligent motor control flop to red flag；

h. Six three-color fault indicating led；(red, green, blue)

i. One yellow state led light；

j. Support line CT power charge for battery；

k. Support timing reset, power on auto reset, remote reset；

l. can be efficiently mounted and unloaded；

m. The structure parts are made of antirust and anticorrosion material；

n. In waking up state(wireless setting model),During 7 minutes, without operate, there will be auto reset.(Tips: in waking up state, FI prohibited fault test)
