摘要： Apparatus is disclosed for detecting a discontinuity or impedance irregularity in an active line, a neutral return line and/or an earth return path of an electrical power distribution network. The apparatus includes means for measuring a change in voltage and/or current flow 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 is due to a discontinuity or impedance irregularity in the active line, neutral line and/or earth return path. The apparatus also includes means for implementing a first algorithm for identifying the discontinuity or impedance irregularity in presence of allowable variation in voltage and/or current flow 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. The apparatus further includes means for comparing a result of the measuring with a reference to provide an indication of the discontinuity or impedance irregularity. A method for detecting a discontinuity or impedance irregularity in an active line, a neutral return line and/or an earth return path of an electrical power distribution network is also disclosed.

摘要： A method is disclosed for detecting a discontinuity or irregularity in a supply line of an electrical power distribution network including a neutral return line and an earth return line. The method includes measuring a property associated with the supply line wherein the property is different when the network includes the neutral return line compared to when the network does not include the neutral return line. The method also includes comparing a result of the measuring with a reference to provide an indication of the discontinuity or irregularity. The property may include a complex impedance associated with the neutral return line or earth return line and/or ambient electrical noise present on the supply line. An apparatus for detecting a discontinuity or irregularity in a supply line of an electrical power distribution network is also disclosed.

摘要： Apparatus is disclosed for detecting a discontinuity or irregularity in a neutral return line of an electrical power distribution network including the neutral return line, an active line and an earth return. The apparatus includes means for measuring a voltage change associated with a deliberate switching of a known impedance in the electrical network wherein the voltage change is due to a discontinuity or impedance irregularity in the neutral return line and means for implementing an algorithm for identifying the discontinuity or impedance irregularity in presence of allowable variations in nominal supply voltage to the electrical network including voltage changes resulting from network operations that mimic or hide a discontinuity or impedance irregularity in the neutral return line. The apparatus also includes means for comparing a result of the measuring with a reference to provide an indication of the discontinuity or impedance irregularity. A method for detecting a discontinuity or irregularity in a neutral return line of an electrical power distribution network is also disclosed.
