SNOVA Earth Fault Indicator is a device used to detect ground fault in power system. It Widely used in various ring cabinets, high/ Medium or low -voltage switch gear and cable branch box in power system, can accurately and reliably detect the fault section and fault type of power grid in the Low/medium voltage network. 

 It can monitor the ground current in the circuit, and send a signal when the circuit ground fault occurs, so as to remind the power system maintenance personnel to take necessary measures to repair it in time.

Ground fault is one of the common faults in the power system. It may have a serious impact on the normal operation of the power system, such as equipment overload, burn, failure, etc. The purpose of the ground fault indicator is to help the power system discover and locate the ground fault in time, so as to avoid the occurrence of accidents, reduce the time of system outage, and ensure the reliable operation of the power system.

       

SNOVA  earth fault alarm indicator has the characteristics of high precision and automation.

 When the ground fault sensor detects the ground fault current and the current is greater than or equal to the set value, the ground fault sensor sends a signal to the display unit through the cable.

The display unit will display the alarm signal, at the same time, the ground fault LED will blink.

It also has low voltage battery reminder, automatic reset, manual reset, SCADA system testing, remote indication functions.

The SNOVA ground fault indicator can also improve the operation efficiency and safety of the power system, reduce maintenance costs, shorten maintenance cycle, improve work efficiency, and thus reduce the operation risk and maintenance cost of the power system. It can be seen that the Snova ground fault indicator is one of the indispensable equipment in the maintenance of power system.
