Investigation of the Impact of Voltage Sags and Temporary Interruptions on 3-Phase Induction Motors

배전계통 순간전압강하 및 순간정전이 3상 유도전동기에 미치는 영향 검토

This paper describes the various characteristics of voltage sags and temporary interruptions which can affect the functions of 3-phase induction motors. These assorted characteristics include motor speed loss, voltage recovery, motor reacceleration, and transient characteristics. An experimental study on induction motor behavior was also carried out to confirm these impacts. Besides, sequential voltage sags of short duration were considered for this paper. The results show that the occurrence of the second voltage sag after the first one may affects the induction motor adversely.
