Overhead Line Fault Indicator With LED Monitor

 Overhead Line Fault Indicator with LED Monitor  Description   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 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  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: l real-time sampling of current per cycle；        l ultra low power real-time sampling； l When line current value≧5A，CT can supply meet the indicator power requirement l Sampling accuracy:  I<10A±1%，I>10A±2% l Sensor factory automatic calibration, to ensure consistency； l intelligent motor control flop； l Support remote, telemetry, remote control, remote adjust； l 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
