  • Electronic grounding system for electrical distribution systems
    Patent number: 4551633
    Abstract: A grounding system for grounding the neutral conductor of an electrical distribution system. A point of reference potential with respect to true earth ground potential is provided. An amplifier has a first input connected to the reference potential and a second input connected to the grounded neutral conductor. The amplifier provides an output signal indicative of the difference between the undesired stray voltage on the grounded neutral conductor and the reference potential. The amplifier develops the output signal across the secondary winding of an output transformer. One terminal of the output transformer is connected to the grounded neutral conductor of the distribution system. The other output terminal of the transformer is connected to true earth ground by way of an auxiliary ground path having a finite resistance.
