摘要：A watthour meter is provided with the ability to maintain a clock and calendar. One or more demand threshold values (16) are defined and associated with periods of electrical demand. The demand meter also defines (14); periods of time that represent demand intervals and, during each demand interval, electrical energy consumption pulses (62) are accumulated (63) in order to represent the electrical consumption during the demand interval period. The magnitude of electrical consumption that takes place during each demand interval is compared (80) to one (78) of the plurality (76) of demand thresholds in order to determine if the demand threshold for the current period of time has been exceeded. If it is determined that the demand threshold has been exceeded, the demand meter of the present invention outputs a signal to a load shed relay (32); in order to shed a preselected nonessential electrical load (44) so that the electrical energy demand of the consumer is reduced.
