What is the difference between 'star' and 'delta' connections in a three-phase electrical system?



The key difference between star (also known as wye) and delta connections in a three-phase electrical system lies in how the three-phase windings are interconnected and the relationship between the line voltage, phase voltage, line current, and phase current. In a star connection, one end of each of the three windings is connected to a common point, called the neutral point or star point. The other ends of the windings are connected to the three lines.....
