Overhead Line Short-circuit And Grounding Fault Indicator Fault Smart-grid

From the past experience of the couple of years, we are engaged in exporting and supplying of Overhead Line Short-Circuit And Grounding Fault Indicator Fault Smart-Grid

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 value 5A CT can supply meet the indicator power requirement
