Star Delta Power Connection. We use it to reduce the starting current of the motor without using any external device or apparatus. One problem associated with this. Star connections are mainly required for the power transmission network for longer distances, whereas in delta connection mainly in distribution networks and is used for shorter distances.

The star connection of three resistors or branches also looks like the english alphabet y so sometimes the star network or connection is also referred to as y or wye connection. Delta connected load, it is opposite to star connection that is, phase voltage = line voltage, line current = √3×phase current. The power ratio between star to delta is1:3.
Controlling the interchanging star connection and delta connection of an ac induction motor is achieved by means of a star delta or wye delta control now motor terminal connection change from star to delta connection.
One problem associated with this. Delta connection is also known as mesh connection because its structure is like a mesh, that is, a closed loop which is planar. Ra is resistance at a, rb is resistance at b, rc is resistance at c in star connection. The starting torque of the motor, if it is connected in delta connection, compare equation 7 and 8. This configuration of voltage sources is characterized by a common connection point joining one side of not surprisingly, the resulting equations for a δ configuration are as follows: We'll also know voltage and current relationship in both the connections, and where these connections. Learn how star delta starters work, why we use them, where we used them and the math behind how they work. In this video, we'll learn in detail about star and delta connection.
