Harmonic Distortion Mitigation Methods for Power Systems

This document discusses the challenges of harmonic distortion in modern power systems caused by non-linear loads like variable frequency drives (VFDs) and rectifiers. It compares three mitigation methods—baseline VFDs, input trap filters, and 12-pulse transformers—and explains how a 12-pulse transformer can meet IEEE 519-92 standards by canceling the 5th and 7th harmonics.
