Embodiment Construction

[0010] refer to figure 1 , the example power distribution circuit 10 for a building 12 is configured in a known manner to supply power from a power source 14 via a power outlet 16 . The power outlet 16 includes a hot terminal 18 , a neutral terminal 20 and a ground terminal 22 . The live wire terminal 18 , the neutral wire terminal 20 and the ground wire terminal 22 are electrically connected to the live wire 24 , the neutral wire 26 and the ground wire 28 respectively. The live wire 24 and the neutral wire 26 are electrically connected to the power source 14 through the fuse box 30 . Of course, other configurations are also possible.

[0011] Power supply 14 has an associated resistor R S , live wire 24 has an associated resistance R 1 , the neutral wire 26 has an associated resistance R 2 .

[0012] Embodiments of the power distribution test system 32 may include a live terminal 34 , a neutral terminal 36 , and a ground terminal 38 . The live terminal 34 , the neutral...

Abstract

A diagnostic system for a power distribution circuit including a line, neutral and ground may include a switch configured to electrically connect the line and neutral, a first sensor configured to sense a line to neutral electrical parameter, and a second sensor configured to sense a neutral to ground electrical parameter. The system may also include a processor configured to close the switch, to observe at least some of the sensed electrical parameters before and after the switch is closed, and to identify a fault condition in the line or neutral based on the observed electrical parameters.

Description

technical field [0001] The invention relates to a power distribution circuit diagnosis system, in particular to a diagnosis system for a power distribution circuit including live wires, neutral wires and ground wires. Background technique [0002] Typically domestic homes and commercial buildings are wired to provide power via electrical outlets. Examining such wiring to identify faults by its extent or layout may be time consuming, expensive, and / or impractical. [0003] Existing diagnostic units may electrically connect the power supply across the line-to-neutral, line-to-ground, and neutral-to-ground wires of the power distribution circuit. If wired properly, the power is turned on when the power is connected across the line to neutral or line to ground wires. If the wiring is not proper, the power will come on when the power is connected across neutral to ground. Contents of the invention [0004] The present invention provides a diagnostic system for an electrical ...
