RELAY AND TIMER BASED AUTOMATIC STAR-DELTA STARTER

Abstract Power is the basic necessity for the economic development of the country. The power should be handled efficiently to meet the requirement. The proposed paper presents the effective usage of The Automatic Star- delta starter in the particular applications. The delta- star module is interfaced with the existing star-delta starter. When starting a motor creates some problem to solve these issues, star – delta starter comes into use. The project is designed to provide low voltage start to induction motor, using relays in star mode first and then to delta mode. This paper concentrates on the design, simulation and practical realization of an electronic based starter.
