USER MANUAL

SNV-EKL3.2 Earth fault and short circuit indicator

Description

 SNV-EKL3.2 Earth fault and short circuit indicator, it Widely used in various ring cabinets, high-voltage switch-gear and cable branch box in power system, can accurately and reliably detect the fault section and fault type of power grid. The use of Earth fault and short circuit indicator is an efficient way to check cable fault, and is an effective way to improve the operation level of distribution network and the efficiency of fault handling. The design uses electromagnetic induction, toelectric conversion, iber transmission and single chip microcomputer control technology to make fault alarm with high accuracy and strong anti-interference ability.

Equipped with fault remote transmission port, suitable for distribution network automation; Â Battery low power alarm indication;Â Low-power design, high-capacity lithium battery power supply, long battery life (more than 8 years); external structure using card or lock design, the whole machine is easy to load and unload.
