Star Delta Power connection
The star delta starter is a most commonly used starting method of a three phase induction motor. In star delta starting an induction motor is connected in a star connection starting period. Then once the motor reaches the 75% above speed, the motor connected through a delta connection.

Delta connection
The terminals of the three branches are connected in star contactor to a common point. The network formed point is known as a star connection. The three branches of the network are connected in second (delta) contactor. The main and delta contactor forms a triangle loop, It called as a delta connection.
Star connection
In a star connection, the starting and finishing point ends of the three coils connected together are known as a common point called a neutral point. But in delta connections, there is no neutral point. The end of each coil is connected to the starting point of the second coil which means that opposite terminals of the coil are connected together.
