电能表试验中奇次谐波和次谐波的频谱分析

Spectral Analysis of Odd Harmonic and Subharmonic Waves for Watt\|hour Meter Tests

对于电能表电流线路中存在畸变波形、引起误差的情况，为在电能表试验中实现该影响试验项目提出了一种新的方法。该法对试验项目中所施加的试验电流波形进行了频谱分析，为通过试验装置的计算机软件进行检定提供了理论基础。

A new method to realise some of the test items for watt\|hour meters which reflect the affection of the wave distortion in current circuit and its error is introduced.The testing current waveshape have been spectrally analysed,thus providing the theoretic basis for the verification of these items by using software that works as a part of the testing devices.
