A REVIEW ON HARMONIC CURRENT AND VOLTAGE ANALYSIS IN TRANSFORMER FOR LOSS DIMINUTION

Harmonics appear in electrical power system with such non-liner loads as electrical are furnaces, welding units, adjustable speed drives, accelerated aging of insulation, decrease in reliability of electrical power system Besides, harmonic voltage is also rising according to the rising of harmonic current. Harmonic current and voltage may basis (cause) rising of loss in receiving power transformers. However, systematic analysis of the loss of receiving power transformers has not been studied. The authors has been tried to analyze the relationship between loss in receiving transformers and harmonics. In this paper presents the studies of harmonics and inrush current in transformer for loss diminution
