Paper Title
To Reduce the Magnetic Inrush Current by Point Wave Switching Method
Abstract
In power transformer initially current is very high magnitude, which cause the produce the harmonics current and
transformer core saturated during the period of initial current and initial current is known as magnetic inrush current. During
this period loss of transformer life, protective devices, as well as power quality is reduce. So this initial current is reducing is
very important, controlled transformer switching can provided to reduce the magnetic inrush current. This paper shows the
practical consideration of elimination magnetic inrush current as well as experimental result of simulation and hardware of
limiting the inrush current. In this paper use a thyristor to control the angle of voltage upto the eight to ten cycles. This paper
shows the theory to explain and characteristics sequential phase enerization depend upon the magnetic inrush current
scheme.
