Power Circuit of Wye(Y) Delta(Δ) Starter

 

Power Circuit of Wye(Y) Delta(Δ) Starter
Automatic Star / Delta Starter with Timer for 3-Phase AC Motors
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.

ratExplanation of the working and operation of Star Delta Automatic Starter with Timer Wiring Installation:

From the left you have the main contactor with the pneumatic timer because your main contactor is always energized, in the Middle you have the Delta contactor with a thermal overload for motor protection in case the motor exceeds the ampere ing set on the thermal overload, on the right you have the Star contactor which is the first contactor to be energized with the main contactor then when the timer reaches its time limit the Star contactor de-energizes and the Delta contactor energizes and the Motor is running at full load.
