Hence, the star (wye) connection of the 3 phases is obtained, when either the beginnings or the ends of the 3 phases are connected together and the 3, not connected wires are used as leads. Instead of connecting the ends of the phases to the neutral, the beginnings of the phases T1, T2, and T3 can be connected together leaving the ends T4, T5, and T6 as leads. This kind of connection is the star or wye connection because the schematic diagram of this connection resembles the letter Y. This is shown schematically in the Figure below. The ends of the three phases T4, T5, and T6 can be connected together at a common point called the “neutral point” leaving the phase beginnings as leads. In the star connection, either the start or all the finish ends of the three windings are connected together. The 3 phases of a 3-phase winding can be connected in two different ways as per the figure shown below. A little sometime afterward, the motor is connected to a delta connection. Initially, the motor is connected to the start of the connection. Star-delta starter starts the motor by reducing the initial current. Normally starter is used for the smooth starting of a motor. Star-delta connection is one type of starting method of 3 phase AC induction motor. A star connection is a 4 wire system, whereas a Delta connection is a 3 wire system. Star and delta are the two basic three-phase connections.
