The metering error considers the non linear effect of the voltage coil and current coil in watt hour meter under different order of harmonics and different distortion degree of input waveform.
计量误差考虑了电度表电压线圈和电流线圈在不同的谐波次数以及谐波大小时的非线性效应。

The traditional measure method of the power withstand test is to use the voltage meter, ammeter, power analyzer, frequency analyzer etc to measure the waveform and parameters of the power signals.
传统的工频耐压试验是通过电压表,电流表,功率分析仪,频谱分析仪等等来分别测量波形及其各个参数的。

The transport cost per cubic meter of natural gas is gradually decreased in waveform with the rising of transportation volume per day, finally turns to a relatively stable value.
