What is the output current of the inverter to be measured? Why not use the current clamp meter?
This is determined by the output characteristics of the inverter.The output waveform of the inverter is determined by its modulation mode and switching frequency.
Personal recommend the use of AnyWay variable frequency power test system, its wide frequency, wide width value, phase measurement, suitable for arbitrary waveform modulation mode, voltage current bandwidth of 30KHz, bandwidth of 20KHz, the highest sampling frequency of 250kHz, fully meet the requirements of measurement of variable frequency power, full range accuracy, is currently the only one high precision frequency measurement equipment. In particular, the introduction of the ATITAN frequency conversion power standard source, but also to fill the gap at home and abroad, you can also look at the relevant news online, a lot of reports in this regard.
There may be sinusoidal PWM modulation, PWM modulation or non sinusoidal waveform, harmonic content of output is high, the fundamental frequency is not necessarily 50Hz waveform, so if the clamp current meter measurement, bandwidth is not enough, in addition, a table cannot be used to measure the frequency of electric quantity.
