FAK8S-1 Ground Short Fault Indicator
Overview
When there is a short circuit or a ground fault in the power supply line,the electromagnetic field generated by the short circuit or the ground current changes, so that the measuring coil of the sensor fixed on the cable generates a pulse signal, and when the value of the pulse signal reaches or exceeds the set fault current value When the fault indicator automatially remembers the fault status, the fault indicator flashes to indicate the fault, and the fault signal is transmitted to the monitoring center through the remote alarm interface. The fault indicator can quickly and accurately find the fault location of the line and eliminate it in time. Fault, restore grid power.
