EKL 4 series short circuit and ground fault indicator

      This series of products can be widely used in power system, all kinds of ring network cabinet, high voltage switch cabinet and cable branch box, can accurately and reliably detect the fault section and fault types of power grid. It is an effective method to check the cable fault by using the cable type short circuit and the earth fault indicator, which is an effective way to improve the operation level and the accident treatment efficiency of distribution network. The design adopts the electromagnetic induction, photoelectric conversion, signal optical fiber transmission and single-chip microcomputer control technology makes the fault alarm with high accuracy and strong anti-interference ability; a fault remote port, suitable for distribution automation; a low battery warning indicator; design of low power consumption, high capacity lithium battery, battery operating life long (more than 8 the external structure of the year); the clamping or lock design, simple and convenient loading and unloading  OR
