5.3.9 Measurement of main circuit voltages, currents and power

Measurement of voltages and currents

Since the voltages and currents on the inverter power supply and output sides include harmonics, accurate

measurement depends on the instruments used and circuits measured.

When instruments for commercial frequency are used for measurement, measure the following circuits using

the instruments given on the next page.
