Description

 SNV-EKL4 short circuit and earth fault 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 cable type short circuit and grounding fault 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, photoelectric conversion, signal optical fiber 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;  Battery low power alarm indication; 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.

Function character：

1) Intelligent detection of short-circuit and ground fault and through the corresponding LED on the panel to indicate fault.

2）Monitor panel designed with button, it is convenient for reset or test.

3）The pulse width time of fault current can be set to prevent incorrect fault indication caused by surge current.

4）It can reset and detect the remote fault indication device remotely.

5）It can provide switch volume for external devices through remote contact.

6）It can choose the reset time after fault happen (when purchase, it need to tell factory to set,default 8hours).

7）Remote fault indicating can be made by external lamp.

8）It can choose the short circuit alarm current (when purchase, it need to tell factory to set).

9）Earth fault alarm current set in factory

10）Low battery display and alarm through press the “Test/reset” key by 3seconds.
