Abstract
An electric watthour meter includes apparatus for delaying a seasonal rate change until data accumulated in the meter is read out. Dates in a rate-change library, consisting of dates on which a rate change is authorized, are compared each day with the current date. When a match between a rate-change date and the current date is found, an arming signal is generated. The arming signal remains ineffective until a reset signal is generated at the completion of meter reading. Following the reset signal, the arming signal is reset.
Claims6
An electric watthour metering system of a type responsive to at least first and second seasonal billing rates comprising:
- means for measuring a power consumption;
- means responsive to chance means for accumulating said power consumption to measure an energy consumption during at least first and second billing rate periods;
- a clock/calendar effective for producing a date signal and a time signal;
- said change means responsive at least to said date signal for performing a change between said first and second seasonal billing rates;
- means for producing a reset signal effective for resetting at least one element in said electric watthour metering system;
- and
- means for delaying an effect of said change means until said reset signal is produced.
A method for watthour metering responsive to at least first and second seasonal billing rates, comprising:
- measuring a power consumption;
- accumulating said power consumption to measure an energy consumption in response to change in at least said first and second billing rates;
- producing a date signal and a time signal;
- changing between said first and second seasonal billing rates in response to at least said date signal;
- producing a reset signal effective for resetting at least one element in said electric watthour metering system;
- and
- delaying said changing until said reset signal is produced.
