An engine friction monitor uses commanded torque and measured torque to provide a prognostic feature to identify failure modes of an engine that causes the engine from delivering the commanded torque.

Engine friction monitor

Systems and methods of providing fault protection on direct current (DC) feeds to various engine or generator set components are provided. In some embodiments, generator set includes a ground fault device 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 of a first current in a first wire with a second current in a second wire between the DC power distribution circuit and the subsystem. In response to detecting the fault condition, the ground fault device is configured to disconnect the subsystem.
