Abstract: In every industries non-linear load such as single-phase diode rectifier, converters, inverters, low voltage power supplies, SMPS, personal computers etc are exists. In every three-phase system the lowest and significant order of harmonic will be 5th harmonic after the fundamental. This harmonics incurs losses in the form of heat dissipation and also contribute to eddy currents and core losses. This extra heat have significant impact in reducing the operating life of electrical instrument especially transformer insulation. This paper provides information on harmonic mitigation techniques for power quality improvement.
