Abstract

See full text

A system and method for non-intrusive fault detection of a ground fault in a communication channel is provided. A bias voltage may be established on a first portion of the communication channel and a second portion of the communication channel. A first voltage may be detected across a first resistor electrically connected to the first and second portions of the communication channel. Data indicative of whether the ground fault exists in the first or second portions of the communication channel may be provided based on the detecting.
