Abstract

A power monitoring system includes a plurality of current sensors suitable to sense respective changing electrical current within a respective conductor to a respective load and a conductor sensing a respective voltage potential provided to the respective load. A power monitors determines a type of circuit based upon a signal from at least one of the current sensors and a signal from the conductor, wherein the type of circuit includes at least one of a single phase circuit, a two phase circuit, and a three phase circuit. The power meter configures a set of registers corresponding to the determined type of circuit in a manner such that the configuring is different based upon each of the single phase circuit, two phase circuit, and three phase circuit suitable to provide data corresponding to the determined type of circuit.

First claim

We claim:

1. A system comprising:
(a) an elongate support board;
(b) said elongate board electrically interconnected to at least four current sensors by a respective flexible wire between said elongate circuit board and respective ones of said at least four current sensors;
(c) each of said current sensors spaced apart along a length of said elongate support board, and spaced apart from said elongate support board, suitable that wires from respective circuit breakers pass through a respective said current sensor;
(d) a set of electrical traces are supported by said elongate support board and electrically interconnected to a respective said current sensors;
(e) a first set of at least four board connectors supported by said elongate support board that receives signals based upon signals from a respective one of said at least four current sensors;
(f) each of said four current sensors is a split core current sensor that is suitable to be opened with a respective said conductor to be inserted therein and suitable to be closed with said respective said conductor maintained therein;
(g) each of said four current sensors interconnected with said respective flexible wire to a respective one of a second set of at least four current sensor connectors at a respective terminal portion thereof, where a respective one of said second set of current sensor connectors detachably interconnect with a respective one of said first set of board connectors supported by said elongate support board, such that the spacing between each said respective flexible wire connected to said circuit board are spaced apart to match a respective said conductor extending out from a respective circuit breaker of an electrical distribution panel.

2. The system of claim 1 wherein said elongate support board extends along a length of said circuit breakers.
