Overhead Line Fault Indicator Type JDG
What is Fault Indicator's Function?
With the function of distant signal transmission,Overhead Line Fault Indicator type JDG is a kind of automatic monitoring device designed for loop grid distribution system of the urban and rural power grid.
Why Should we Use a Fault Indicator?
---- Rapidly indicate the fault circuit and fault point, lessen the blackout area.
---- Shorten the time of troubleshooting, improving the reliability of power supply.
---- Accurately indicate the instant fault, which is conducive to rule out the power supply problems.
----- Providing techniques to find the permanently hidden fault point.
----- Shorten the time to find the fault point, reduce the labor intensity of patrol personnel.
----- Defining the responsibility of the fault area and responsible people.
----- Avoiding the impact to the electrical equipment because of repeatedly traditional patrollines pulling.
