Earth Fault and Short Circuit Indicator

Earth Fault and Short Circuit Indicator EKL1B

Short circuit fault alarm indication

Short-circuit fault sensors installed on 3 single phase cables, monitoring the current changes of the power supply lines, when the current change value reach or exceed Threshold currents for short circuit alarm (this value can be set as per user requirement),the short circuit fault sensors output alarm signal, through optical fiber the signal will be sent to the indicator host, the corresponding fault indicator light will flash to alarm the short circuit fault.

Earth fault alarm indication

Earth fault sensor installed on the bifurcation unshielded part of three-phase cable, detecting the zero sequence current value of the three-phase cable, when its value reach or exceed Threshold currents for grounding fault alarm (this value can be set as per user requirement), the earth fault sensor outputs alarm signal through optical fiber, which will be sent to the indicator host, and the earth fault indicator light will flash to alarm the earth fault.
