摘　　要：基于感应式电表与全电子式电表的工作原理,推导出各自在谐波下的数学表达式,并分析出电表计量误差的影响因素,结合理论计算与仿真分析,得到谐波对电表计量影响的结论。Based on the operating principles of the inductive and full-electronic electricity meters, this essay intro- duces the derivations of the mathematical expressions of them under the influence of harmonics as well as the analy- sis of the influencing factors which cause the metering errors. Besides, with the combination of theoretical calculation and simulated analysis, the conclusion that harmonics have an influence on the electricity meter measurement is drawn.
