摘要
非线性负载引起交流正弦波畸变产生谐波,污染工频电网。本文对非正弦波有功电能正确计量,电子式电能表在含有谐波的电能计量中产生误差的原因及电子式电能表的谐波影响检定方法作了介绍。
The nonlinear load causes the distortion of the AC sine wave and produces harmonic, polluting the power frequency grid. This paper introduces the correct measuring method of the non-sine wave active energy, the reason of the error of the electric Watt meter under the harmonic condition and the assess method of affection of the harmonic on the electric Watt meter.
