Abstract
A method for storing information within a utility meter that includes storing a data stream comprising a plurality of data values regarding a metered quantity delivered to a load corresponding to a plurality of time periods, wherein the plurality of data values are stored sequentially based on their corresponding time periods. The method also includes responsive to a power outage, inserting into the data stream a time stamp corresponding to a time period in the plurality of time periods in which the power outage occurred.
Claims14
A method for storing information within a utility meter, comprising:
- a) storing a data stream comprising a plurality of data values regarding a metered quantity delivered to a load corresponding to a plurality of time periods, wherein the plurality of data values are stored sequentially based on their corresponding time periods;
- and
- b) responsive to a power outage, inserting into the data stream a time stamp corresponding to a time period in the plurality of time periods in which the power outage occurred.
A metering circuit, comprising:
- a metrology circuit operably coupled to a load, the metrology circuit configured to generate energy consumption values based on the voltage and current provided to the load;
- at least one memory;
- and
- a processing circuit configured to
- generate information regarding a metered quantity delivered to a load corresponding to each of a plurality of time periods;
- store, in the at least one memory, a data stream comprising a plurality of data values regarding the metered quantity corresponding to the plurality of time periods, wherein the plurality of data values are stored sequentially based on their corresponding time periods;
- and
- responsive to a power outage, inserting into the data stream a time stamp corresponding to a time period in the plurality of time periods in which the power outage occurred.
