摘要：

This paper describes the implementation of a sampling wattmeter for the measurement of active and reactive power over the 50-Hz-6-kHz frequency range, 20-600-V voltage range, and 0.05-80-A current range. The wattmeter is capable of measuring sinusoidal and distorted voltage and current signals with up to 100 harmonics of the fundamental frequency component. Details of the system design, measurement techniques, and significant sources of uncertainty are presented.
