Temperature Profiling in an Electricity Meter
An arrangement includes a plurality of electricity meters and a control station. Each of the plurality of electricity meter includes a memory storing temperature information regarding the electricity meter, and a communication device. The control station is configured to receive temperature information from each of the plurality of electricity meters, for example, by way of the communication device of the electricity meters. The control station is also configured to process the temperature information from the plurality of electricity meters to generate at least one diagnostic value.
1 . An arrangement, comprising:
a plurality of electricity meters, each electricity meter including a memory storing temperature information regarding the electricity meter, and a communication device;
a control station configured to receive temperature information from the plurality of electricity meters, the control station further configured to process the temperature information from the plurality of electricity meters to generate at least one diagnostic value.
2 . The arrangement of claim 1 , wherein the diagnostic value includes information identifying one or more of the plurality of electricity meters to be scheduled for service.
3 . The arrangement of claim 1 , wherein the diagnostic value includes a value representative of a predicted meter failure rate.
4 . The arrangement of claim 1 , wherein the control station is further configured to:
evaluate filtered temperature information based on temperature information from each meter for a plurality of time periods;
and determine an adjustment of a metering circuit parameter for at least a first meter, based on the evaluation of the filtered temperature information;
communicate a signal to the first meter, the signal including information representative of the determined adjustment.
5 . The arrangement of claim 4 , wherein the control station processing circuit is further configured to determine the adjustment such that the adjustment is an adjustment of a metering circuit clock of the first meter.
6 . The arrangement of claim 4 , wherein the control station processing circuit is further configured to determine the adjustment such that the adjustment is an adjustment of an energy consumption calculation circuit of the first meter.
