Fully automatic star delta starter control circuit diagram. Block diagram of automatic star delta starter due to the wide variety characteristics of the induction motor it plays the premier role in the industrial sector. There is minor correction is require to change printed in boxes sequence of 3 phase wires from w2 v2 u2 to w2 u2 v2 to get delta connection properly. A star delta starter is a type of reduced voltage starterwe use it to reduce the starting current of the motor without using any external device or apparatus. In this tutorial we will show the star delta y δ 3 phase induction ac motor starting method by automatic star delta starter with timer with schematic power control and wiring diagram as well as how star delta starter works and their applications with advantages and disadvantages. This equipmentappliance reduces starting current and starting torque. This is a big advantage of a star delta starter as it typically has around 13 of the inrush current compared to a dol starter.
Automatic star delta starter design normally consists of three contactors an overload relay or circuit breaker and a timer for setting the time in the star position starting. Some of those are self starting rugged construction high efficiency good power factor and ease of control etc. Here the circuit diagram of star delta starter explained in detailhere you will learn the connection of star delta starter with three phase motorthe power circuit diagram and control circuit diagram of an automatic star delta starter are explained belowlets understand the star delta starter diagram.
