ABSTRACT: Electrical grid power quality is a global issue. The
grid must supply electricity at sinusoidal voltages and currents without
frequency or amplitude fluctuations. Harmonics from non-linear loads change the
stable reference point voltage waveform and cause other problems. Harmonic
reduction is essential for grid health. Electrical and electronic equipment
users, manufacturers, and suppliers all contribute. This article presents a
case analysis of the plastic processing industry, which has historically
struggled with a difficulty related to the fifth harmonic. Unwanted harmonics
are reduced by using a single-tuned passive filter, a double-tuned passive
filter, and a second-order damped filter. The total harmonic distortion is
almost identical, but the second-order damped filter provides the best harmonic
mitigation, meeting the requirements of the IEE 519-1992 Standard.
