초록
In this study, the method for the measurement of harmonics at nonsinusodial signal, which utilizes two synchronized high precision digital multimeters has been developed. The harmonics of voltage and current waveforms were computed from the acquired digitize samples through the DMMs and using developed software which based on FFT algorithm. The system can be used as a reference system to calibrate harmonic analyzers.
