EKL2 cable fault indicatorDetailed product description：

Product Introduction:
The EKL2 cable fault indicator is a device installed in box transformers, cable branch boxes, and ring main units to indicate cable fault branches. A device used to indicate the flow of fault current. Once a short circuit fault occurs in the circuit, the line patrol personnel can use the flashing alarm display on the indicator to quickly determine the fault section, branch, and fault point. Completely changing the outdated practice of blind line inspection, segmented closing and trial power transmission to find faults in the past, greatly improving work efficiency, effectively shortening power outage time, and enhancing power supply reliability and economic benefits.

1、 Cable line short circuit fault indicator
Short circuit fault criterion
(1) 1t ≥ 600A, 1t is the starting value of sudden variable current
(2) △ 1 ≥ 0.510 △ 1 current change rate 10 is the line current before the short circuit
(2) 1=0 1 is the current after a line fault
(4) 0.02S ≤ △ T ≤ 2S △ T is the sudden change time of current

2、 Cable line grounding fault indicator
Short circuit fault criterion
When detecting faults, the zero sequence current changes by more than 20A

3、 Cable line grounding short circuit fault indicator
Cable line grounding short circuit fault indicator, each set comes standard with two short circuit indicators and one ground indicator. The short circuit indicator detects short circuit faults, while the ground indicator detects ground faults. When used together, the two can detect both ground and short circuit faults.
