Stationary battery and dc power systems used in switchgear and control applications are typically designed and operated as a floating from ground system which means that there is no intentional low resistance or solid connection to ground from either the positive polarity or negative polarity of the dc system.
Monitoring earth faults in unground dc systems is vital to prevent any sudden tripping in the system.
Earth faults can occur without any indication and are difficult to identify. Hence a system to monitor the earth faults in a DC system is vital.
Motwane’s MGFL is worlds lightest battery powered instrument to pinpoint multiple earth faults in high interference environment.
