Star delta connection: These three-phase AC circuits

These three-phase AC circuits are divided into star and delta connection circuits. Both circuits differ from each other concerning some parameters. Let's study the difference in detail. Star connection is one type of three-phase AC circuit. Star connection is denoted by 'Y'. The replacement of delta or mesh by equivalent star connection is known as delta – star transformation. The two connections are equivalent or identical to each other if the impedance is measured between any pair of lines. A star delta starter is the most commonly used method for the starting of a 3 phase induction motor. In star delta starting an induction motor is connected in through a star connection throughout the starting period. Then once the motor reaches the required speed, the motor is connected through a delta connection. In this video, we clearly explain the Star Delta Power Connection and Contactor Motor Star Delta Wiring in a simple, step-by-step, and practical way. 💡This ...
