In wye or star connection _____________ of the three phases are joined...
In a three-phase alternator, there are two common methods of connecting the three phases: wye (Y) connection and delta (Δ) connection. The question specifically refers to the wye or star connection.
In a wye or star connection, the similar ends of the three phases are joined together within the alternator. This means that the end of each phase winding that is closest to the neutral point is connected together. The neutral point is typically connected to the system neutral or ground.
Explanation:
- Wye or Star Connection: In a wye or star connection, the three phases are connected in such a way that the end of each phase winding that is closest to the neutral point is joined together. This forms a star or wye shape, hence the name. The neutral point is typically connected to the system neutral or ground.
- Similar Ends Joined: In this type of connection, the similar ends of the three phases are connected together. This means that the end of each phase winding that is closest to the neutral point is joined together.
- Purpose of Joining Similar Ends: By joining the similar ends, the voltage across each phase winding with respect to the neutral point becomes the line-to-neutral voltage. This is the voltage that is commonly used in electrical systems. It is also the voltage that is measured using a voltmeter in a wye connected system.
- Advantages of Wye Connection: The wye connection has several advantages, including the ability to provide a neutral point for grounding, the ability to supply both single-phase and three-phase loads, and the ability to balance the current in the system.
- Other Connection Types: In contrast to the wye or star connection, the delta (Δ) connection involves connecting the ends of the phases in a triangular or delta shape. In this type of connection, the line-to-line voltage is equal to the line-to-neutral voltage multiplied by the square root of three.
Therefore, in a wye or star connection, the similar ends of the three phases are joined together within the alternator. This type of connection allows for the generation of the line-to-neutral voltage, which is commonly used in electrical systems.
