초록
The precise measurement of consumed power for a given time is very important in the energy management aspect. Up to days, most power meter has been used and designed for use on circuits in which the voltage and current are essentially sinusoidal. Recently the increase of switching element in power system causes the current and voltage with harmonics. Therefore, power energy involving harmonics is supplied to the system and the error of power measurement of watthour meter is existed. In this paper, we present a characteristic analysis by input frequency variation and analytical basis of induction watthour meter considering harmonics.
