Which of the following statements about a three-phase wye connected alternator is correct?

🔍 Key Concepts

• Three-phase wye (Y) connection relationships between line and phase values • Difference between line voltage/current and phase voltage/current • The factor √3 (approximately 1.73) in three-phase systems

💭 Think About

• In a wye connection, think about how each phase winding is connected to the neutral and how the line conductors connect to the ends of those windings. • Ask yourself: in a wye system, are the line conductors measuring across one phase only, or between two different phases? • Consider separate relationships: one for voltage (line vs. phase) and one for current (line vs. phase) in a wye connection.

✅ Before You Answer

• Be clear on which quantities are equal in wye: Is line current equal to phase current, or line voltage equal to phase voltage? • Remember that the √3 (1.73) factor only applies to one type of quantity (voltage or current) in a wye connection, not both. • Double-check that you’re not mixing up the formulas for delta (Δ) and wye (Y) connections.
