  • METHOD AND APPARATUS FOR DETECTING A FAULT IN AN ACTIVE LINE, NEUTRAL RETURN LINE OR EARTH RETURN PATH OF AN ELECTRICAL NETWORK
    Publication number: 20120235825
    Abstract: Detecting a discontinuity or impedance irregularity in an active line, a neutral return line and/or an earth return path of a power distribution network is disclosed. In one aspect, the apparatus is configured to measure a change in voltage and/or current associated with a deliberate switching of a known impedance and/or a naturally occurring random switching of an impedance in the electrical network wherein the change in voltage and/or current flow results from a discontinuity or impedance irregularity in the active line, neutral line and/or earth return path. The apparatus includes an algorithm for identifying discontinuity or impedance irregularity in the presence of allowable variation in voltage and/or current that may mimic or hide a discontinuity or impedance irregularity in the active line, neutral return line and/or earth return path including a reverse current flow through the earth return path.
