Patent ID: 7978446

Claim:
A ground fault detection system for an electrical system, the electrical system having a first electrical component and a second electrical component, the ground fault detection system comprising: a first ground fault detection module configured to detect a ground fault of the first electrical component, and to activate a mode of operation for the first electrical component when a ground fault of the first electrical component is detected; a second ground fault detection module configured to detect a ground fault of the second electrical component, and to activate a mode of operation for the second electrical component when a ground fault of the second electrical component is detected, wherein the first electrical component is isolated from the second electrical component; and a ground fault controller configured to provide a warning in response to receiving, over a data link between the controller and the first and second ground fault detection modules, a report of a detected ground fault of the first electrical component from the first ground fault detection module or a report of a detected ground fault of the second electrical component from the second ground fault detection module.
