Abstract

A system for configuration of power meters.

Claims

1. A method for configuring a power meter including registers comprising the steps of:

(a) receiving by said power meter a plurality of current input signals representative of a current level in a respective conductor;

(b) receiving by said power meter a plurality of voltage input signals representative of a voltage level in a respective said conductor;

(c) configuring said power meter including a set of registers where said set of registers is configured with an initial configuration, where said power meter is configured to determine based upon said initial configuration a first value to include in a first of said set of registers based upon a combination of at least one of said plurality of current input signals and at least one of said plurality of voltage input signals, where said power meter is configured to determine based upon said initial configuration a second value to include in a second of said set of registers based upon a combination of at least one of said plurality of current input signals and at least one of said plurality of voltage input signals,

(d) providing said power meter together with said initial configuration a first data set for a first configuration of said set of registers of said power meter where said first configuration is configured only when selected to determine based upon said first configuration a third value to include in one of said set of registers based upon a combination of at least one of said plurality of current input signals and at least one of said plurality of voltage input signals where said first data set is stored within said power meter at a location separate from said set of registers, a second data set for a second configuration of said set of registers of said power meter where said second configuration only when selected is configured to determine based upon said first configuration a fourth value to include in one of said set of registers based upon a combination of at least one of said plurality of current input signals and at least one of said plurality of voltage input signals where said second data set is stored within said power meter at a location separate from said set of registers, a third data set for a third configuration of said set of registers of said power meter where said third configuration is configured only when selected to determine based upon said first configuration a fifth value to include in one of said set of registers based upon a combination of at least one of said plurality of current input signals and at least one of said plurality of voltage input signals where said third data set is stored within said power meter at a location separate from said set of registers, wherein said first data set, said second data set, and said third data set are separate from one another, wherein said first data set, said second data set, and said third data set are non-overlapping with one another;

(e) said power meter selecting with a selector a first selected data set that includes only one of a first one of said first data set, said second data set, and said third data set for a first load associated with at least one of said conductors for a first set of said set of registers, where said first selected data set configures said first set of said set of registers and overwrites at least a first portion of said initial configuration in such a manner that said first portion of said initial configuration is no longer present within said power meter separate from said registers, wherein the output of said first set of said set of registers based upon said initial configuration is different than the output of said first set of registers based upon said first selected data set;

(f) said power meter selecting with said selector a second selected data set that includes only one of a second one of said first data set, said second data set, and said third data set that is different than said first selected data set for a second load associated with at least one of said conductors for a second set of said set of registers, where said first set of registers is different than said second set of registers, where said second selected data set configures said second set of said set of registers and overwrites at least a second portion of said initial configuration in such a manner that said second portion of said initial configuration is no longer present within said power meter separate from said registers, where said first portion and said second portion are different from one another, wherein the output of said second set of said set of registers based upon said initial configuration is different than the output of said second set of registers based upon said second selected data set;

(g) wherein said first data set is a configuration suitable for a single phase circuit, said second data set is a configuration suitable for a two phase circuit, said second data set is a configuration suitable for a three phase circuit, and said first selected data set and said second selected data set are suitable for different ones of said single phase circuit, said two phase circuit, and said three phase circuit;

(h) providing by said power meter data from said set of registers in accordance with said first portion and said second portion.

2. The power meter of claim 1 wherein said selector said selects a first one of said first data set, said second data set, and said third data set for said first load associated with at least one of said conductors for said first set of said set of registers.

3. The power meter of claim 2 wherein said selector said selects a second different one of said first data set, said second data set, and said third data set for said second load associated with at least one of said conductors for said second set of said set of registers.

4. The power meter of claim 3 wherein said selector said selects a third different one of said first data set, said second data set, and said third data set for a third load associated with at least one of said conductors for a third set of said set of registers, where said third set is different than either of said first set and said second set.

5. The power meter of claim 4 wherein said first load is a three phase load.

6. The power meter of claim 5 wherein said second load is a single phase load.

7. The power meter of claim 6 wherein said third load is a two phase load.
