| 摘 要： | 针对谐波条件下感应式和电子式电能表2种电能表的计量误差进行了分析和讨论,指出现有感应式电能表无法区分线性与非线性负荷,对于非线负荷其计量电能小于基波电能;而电子式电能表虽能对线性和非线性负荷加以区分,但同样存在计量误差,计量方式不合理的问题,提出一种较合理的改进计量方式.

| Abstract: | Measurement errors of induction meter and electronic meter under harmonic conditions have been analysed and discussed.It has been pointed out that the current induction meter could not distinguish linear and non-linear loads.The measured electric energy under non-linear load is lower than fundamental energy.The electronic meter could distinguish linear and non-linear loads but has problems such as measuring error and unreasonable measuring methods.An reasonable improved measuring method has been proposed. |
