ABSTRACT:
An isolated ground interface apparatus for providing a remote termination point for isolated ground conductors. The isolated ground interface apparatus includes an isolation transformer, a plurality of isolated ground receptacles, and an electrical interface. The isolation transformer establishes a neutral to ground bond and thereby prevents transmission of a common mode voltage from an input power supply to an electrical device. A plurality of isolated ground receptacles provides a separate ground reference point from a chassis ground for preventing transmission of electrical noise to the electrical device. The electrical interface electrically interconnects the isolation transformer, the input power supply, and the plurality of isolated ground receptacles together. The input power supply transmits an electrical current through the electrical interface to the isolation transformer. The isolation transformer provides an isolated ground through the electrical interface to the isolated ground conductor electrically connected to the separate ground reference point of the plurality of isolated ground receptacles. A method of providing electrical current supplied by an input power supply to a plurality of isolated ground receptacles using the electrical interface in a normal mode and a bypass mode.
