摘要
Abstract
AC charging point energy meter with measurement range of 1 (50)A has been designed by adopting wide measurement range metering IC. This meter has better than ± 0.2% metering error for AC active energy in the currentrange of 20mA~50A. It has the capability to resist DC component and even harmonic, and it meets the 3rd ~ 21rd harmonic influence quantity requirement set by standard. Through inspection and field use, it shows that this single phase wide measurement range energy meter can accurately measure the electric energy during the whole charging process of AC charging point.关键词
