EFFECTS OF HARMONICS ON EQUIPMENT

The purpose of this paper is summarize the state-of-knowledge of the e ffects of power system harmonics on equipment. The general mechanisms presented are thermal overloading, disruption, and dielectric stressin g. Quantitative effects are presented or referenced whenever possible. However, many of the effects are can only be qualitatively described. The equipment considered are adjustable speed drives, capacitors, cir cuit breakers, fuses, conductors, electronic equipment, lighting, mete ring, protective relays, rotating machines, telephones, and transforme rs.
