Abstract

A system for isolating electrical ground faults and secondary failures in an electrical system, the system comprising an AC ground isolation state machine for detecting and isolating an AC ground, a DC ground isolation state machine for detecting and isolating a DC ground, a component failure isolation state machine for detecting and isolating a change in a resistance, and a component failure early detection algorithm for determining a failure before using the state machines.
