Methods and apparatus for defining meter data calculations in an electronic electricity meter
First Claim
1. A method for defining meter data calculations in an electronic electric meter, said method comprising:
- storing a set of predefined data calculation instructions in a non-volatile memory of the meter;
storing a first set of vectors in a memory of the meter, the vectors pointing to data calculations of the set of predefined data calculation instructions;
metering a plurality of electrical quantities of a power source;
controlling calculations performed on the metered electrical quantities in accordance with the data calculation instructions pointed to by the first stored set of vectors; and
calculating at least one of a momentary interval quantity, a one-minute meter defined sum, a one-minute user defined sum, a minute FIFO sum, a demand interval sum, and a load profile interval sum.
