Inrush Current Investigation for Single Phase Power Transformers by Means of Magnetic Material Core Characteristics

Abstract

The paper propose a quantitatively study of the inrush current that occurs when a no loaded single phase power transformers is energized. An analytical approached is suggested, that along with various switching parameters, the main magnetic core material characteristics are considered. Thus a comparison between the parameters of the inrush current for different core magnetic materials of a 6 kVA general purpose single-phase transformer is carried out.
