삼상 변압기와 유도전동기에서의 전압 sag에 의한 들입 전류 분석

Analysis of inrush current caused by voltage sag in three-phase transformer and induction motor

This paper studies the effects caused by symmetrical and unsymmetrical voltage sags on three-phase transformer and induction machine. The voltage sag on transformer and induction machine gives rise to inrush current. This inrush current makes sag more severe. These effects depend or many elements such as sag magnitude and duration, type of sag, and fault and recovery voltage instants.
