摘要
In a kilowatt-hour meter for measuring electrical energy consumption from an alternating electrical supply, a microprocessor includes a clock signal generator which is synchronized in phase with the incoming supply frequency. Pulse sampling means controlled by the clock generator sample the incoming voltage and current waveforms at a preselected time instant or instants in each cycle and the sampled data is utilized in the microprocessor to determine energy consumption.
