Detailed Product Description

The Earth and Short Circuit Fault Indicator is an instrument for detecting short circuit and earth faults. This indicator is used in each loop of medium voltage radial networks. In order to avoid serious failure happening to distribution power network, especially in the network where lots of ring main unit with loadbreak switch were used, the upper level system must be tripped within the set time when short circuit or earth fault occurs in the lower level. When tripping and breaking happens, the whole network subjected to the upper level will be powered off. The indicator can locate and indicate the fault section so that the operator can find and trip the fault section quickly according to the alarm signal, this will not only save a lot of working time, but also shorten the system interruption duration and range of power outage.
