Systems and methods for providing ground fault protection on direct current power feeds of engine components

A ground fault device 103 is arranged between a DC power distribution circuit and a subsystem of the generator set. The ground fault device is configured to detect a fault condition based on a comparison by controller 132 of a first current I1 in a first wire with a second current I2 in a second wir...

Summary:A ground fault device 103 is arranged between a DC power distribution circuit and a subsystem of the generator set. The ground fault device is configured to detect a fault condition based on a comparison by controller 132 of a first current I1 in a first wire with a second current I2 in a second wire between the DC power distribution circuit and the subsystem. In response to detecting the fault condition, the controller 132 is configured to disconnect the subsystem by opening switch 131.
