Line Self Powered Intelligent Gird Electrical Fault Indicator 35KV
Product Introduction
Fault indicator refers to a device installed on power lines (overhead lines, cables and busbars) to indicate fault current. Most fault indicators can only distinguish and indicate short-circuit faults by detecting the characteristics of the short-circuit current.
