Abstract :
A software package is described that was developed to perform harmonic analysis on digitized current and voltage waveforms. The authors also report on the measurement and characterization of voltage and current harmonics and high-frequency distortion of a large industrial load. Since waveform distortions often include periodic high-frequency transients, special signal processing techniques were developed in the software to alleviate misleading results of the calculated harmonics. From simultaneous measurements on all three phases, an investigation of harmonic unbalance at the industrial load is discussed. Problems with the installation of a capacitor bank for voltage regulation purposes are also described
