Abstract

A system for energy metering with temperature monitoring that includes a plurality of current sensors, suitable to sense a changing current in a respective power cable, that provide a respective first output. The energy metering system includes a support and current sensors interconnected to the support at spaced apart locations along the support. A temperature sensor that provides a second output and is interconnected to the support. The energy metering system receives the respective first output and the second output and determines characteristics of the energy system based upon the second output.

First claim

What is claimed is:

1. An energy system comprising:
(a) a plurality of at least three current sensors, suitable to sense a changing current in a respective power cable, that provide a respective first output;
(b) an elongate support;
(c) said at least three current sensors interconnected to said elongate support at a set of uniformly spaced apart locations along said elongate support that is consistent with the spacing of a uniformly spaced apart set of at least three power cables each of which is interconnected to a respective one of a uniformly spaced apart set of at least three circuit breakers of a power panel;
(d) at least three temperature sensors that each provide a respective second output;
(e) each of said temperature sensors interconnected to said elongate support at a set of spaced apart locations along said elongate support;
(f) said energy system receives said respective first output from said at least three current sensors and said respective second output from each of said at least three temperature sensors, and (1) determines characteristics of said energy system based upon a plurality of said second outputs to identify one of said at least three circuit breakers that is likely to trip and (2) determines characteristics of said energy system based upon said plurality of said second outputs to identify another one of said at least three circuit breakers that is not likely to trip, while said one of said at least three circuit breakers is identified as said likely to trip.

2. The energy system of claim 1 wherein said current sensors are detachably interconnected to said support.

3. The energy system of claim 1 wherein said current sensors are detachably interconnected to said support by a respective connector.

4. The energy system of claim 1 wherein said temperature sensors are supported by an enclosure where said enclosure encloses one of said plurality of current sensors.

5. The energy system of claim 4 wherein said temperature sensors are enclosed within said enclosure.

6. The energy system of claim 1 wherein said characteristics are used to predict if a circuit breaker associated with a respective power cable is likely to trip.

7. The energy system of claim 1 wherein said characteristics are used to predict if one of a plurality of circuit breakers associated with a plurality of respective power cables is likely to trip.

8. The energy system of claim 1 wherein said characteristics are used to provide an alarm condition.

9. The energy system of claim 1 wherein said characteristics are used to provide a warning condition.

10. The energy system of claim 1 wherein said characteristics are used to provide a normal condition.

11. The energy system of claim 8 wherein said alarm condition is based upon a plurality of said second outputs.

12. The energy system of claim 9 wherein said warning condition is based upon a plurality of said second outputs.

13. The energy system of claim 10 wherein said normal condition is based upon a plurality of said second outputs.

14. The energy system of claim 8 wherein said alarm condition is based upon a relative level of said characteristics.

15. The energy system of claim 8 wherein said alarm condition is based upon an absolute level of said characteristics.

16. The energy system of claim 1 wherein said temperature sensors are supported by said support.

17. The energy system of claim 1 further comprising said plurality of said temperature sensors, each of which is supported directly by said support.

18. The energy system of claim 1 further comprising a plurality of enclosures each of which is associated with a respective current sensor, each of said temperature sensors are supported by a respective said enclosure and each of which provides a respective said second signal.

19. The energy system of claim 1 further comprising each of said plurality of said temperature sensors each of which having a respective said second output wherein said characteristics for one of said power cables is determined based upon a plurality of said respective second outputs.

20. The energy system of claim 1 wherein said plurality of current sensors includes three current sensors, suitable to sense a changing current in a respective power cable of a three phase load, that provide a respective first output, three said temperature sensors each of which having a respective said second output, wherein a first one of said respective said first outputs is associated with a respective first one of said second outputs, wherein a second one of said respective said first outputs is associated with a second respective one of said second outputs, wherein a third one of said respective said first outputs is associated with a third respective one of said second outputs, wherein said characteristics for said load is based upon said three said respective said second outputs.
