    Meters and measuring methods 4.5 Meters and measuring methods Since voltages and currents in the primary and secondary side of the inverter include harmonics, different meters indicate different measured values. When making measurement with the meters designed for commercial frequency, use the following measuring instruments and circuits: When installing meters etc.
  • Page 259: Measurement Of Voltages And Use Of Pt

    Meters and measuring methods 4.5.2 Measurement of voltages and use of PT (1) Inverter input side As the input side voltage has a sine wave and it is extremely small in distortion, accurate measurement can be made with an ordinary AC meter. (2) Inverter output side Since the output side voltage has a PWM-controlled rectangular wave, always use a rectifier type voltmeter.
  • Page 260: Use Of Ct And Transducer

    Meters and measuring methods 4.5.4 Use of CT and transducer A CT may be used in both the input and output sides of the inverter, but the one used should have the largest possible VA ability because an error will increase if the frequency gets lower. When using a transducer, use the effective value calculation type which is immune to harmonics.
