Filed: 1988-07-04
Abstract: PURPOSE:To obtain the reliable electronic watt-hour meter by dividing consumption which is estimated by unit prices by the charge for electric power by the unit prices per unit time and thus calculating the rest use time of electric energy. CONSTITUTION:A power consumption estimated quantity calculating means 1 calculates estimated power consumption in a following specific period from the power consumption per unit time which is obtained so far.
