Patent ID: 7408271

Claim:
A centralized isolated ground interface apparatus for providing a remote termination point for isolated ground conductors, comprising: (a) an isolation transformer for establishing a neutral to ground bond and thereby preventing transmission of a common mode voltage from an input power supply to an electrical device; (b) a plurality of isolated ground receptacles located in remote locations with respect to the isolation transformer for providing a separate ground reference point for each of the receptacles from a chassis ground and for preventing transmission of electrical noise to the electrical device; (c) an electrical interface for electrically interconnecting the isolation transformer, the input power supply, and the plurality of isolated ground receptacles together, whereby the input power supply transmits an electrical current through the electrical interface to the isolation transformer, the isolation transformer providing an isolated ground through the electrical interface to the isolated ground conductors electrically connected to the separate ground reference point of the plurality of isolated ground receptacles; and (d) a bypass switch for bypassing the isolation transformer for allowing service and maintenance to be performed without disrupting the electrical current transmitted to the plurality of isolated ground receptacles.
