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 power monitoring system comprising:
(a) a plurality of current sensors suitable to sense respective changing electrical current within a respective one of a plurality of conductors to a respective load, wherein each of said plurality of current sensors includes a respective sensing conductor wrapped around a respective core, wherein each of said plurality of current sensors at least partially encircles a respective one of a plurality of conductors to a respective load, where each of said respective one of said plurality of conductors is electrically interconnected to said respective load and each of said respective one of said plurality of conductors is electrically isolated from one another;
(b) a plurality of conductors sensing a respective voltage potential provided to said respective load;
(c) a power monitor that receives a respective current signal from each of said plurality of said current sensors from said respective sensing conductor and a respective voltage signal from each of said plurality of conductors, said power monitor determines a type of circuit based upon an analysis of said respective current signal from each of said plurality of said current sensors and said respective voltage signal from each of said plurality of conductors, wherein said type of circuit includes at least one of a single phase circuit, a two phase circuit, and a three phase circuit;
(d) said power meter configuring itself corresponding to said determined type of circuit in a manner such that said configuring is different based upon each of said single phase circuit, two phase circuit, and three phase circuit suitable to provide data corresponding to said determined type of circuit.

2. The power meter of claim 1 wherein said plurality of current sensors includes at least three current sensors.

3. The power meter of claim 2 wherein said plurality of conductors includes at least three said conductor sensing a different respective voltage potential.

4. The power meter of claim 3 wherein said power monitor determines said type of circuit includes said three phase circuit.

5. The power meter of claim 3 wherein said power meter determines said type of circuit includes said two phase circuit.

6. The power meter of claim 3 wherein said power meter determines said type of circuit includes said single phase circuit.

7. The power meter of claim 4 wherein said configuring includes data corresponding to said three phase circuit while omitting data corresponding to at least one of two phase and single phase circuits.

8. The power meter of claim 5 wherein said configuring includes data corresponding to said two phase circuit while omitting data corresponding to at least one of three phase and single phase circuits.

9. The power meter of claim 6 wherein said configuring includes data corresponding to said single phase circuit while omitting data corresponding to at least one of two phase and three phase circuits.

10. The power meter of claim 7 wherein said power meter is free from computing data corresponding to said omitted data.

11. The power meter of claim 8 wherein said power meter is free from computing data corresponding to said omitted data.

12. The power meter of claim 9 wherein said power meter is free from computing data corresponding to said omitted data.

13. The power meter of claim 10 wherein said configuring correspond to MODBUS data.

14. The power meter of claim 11 wherein said configuring correspond to MODBUS data.

15. The power meter of claim 12 wherein said configuring correspond to MODBUS data.
