Intelligent High-Precision Fault Indicator

Overhead lines of 35kV and below for distribution network.

Product Overview

Intelligent high-precision fault indicator independently developed by CYG ET: it integrates intelligent sensor technology, signal processing technology, artificial intelligence technology and information communication technology to realize access to energy at low power consumption, and relies on high-precision information acquisition and wide-range high-precision measurement to record waves, so as to realize accurate fault location of small current grounding system and retrospective inversion of complex fault process, thus effectively shortening the power outage time of line faults and improving the reliability of power supply. In addition, it has the functions of all-wireless power supply-free, rapid deployment based on live installation and dismantling and status monitoring perception, and supports the construction needs of ubiquitous IoT.
