What are the types of connections in a 3-phase component?

• A. Delta and Wye
• B. Series and Parallel
• C. Star and Loop
• D. High and Low

Answer: (A)

In a 3-phase component, the windings are connected in two standard ways: delta and wye.

In a delta connection, the windings form a closed loop like a triangle, with each line connected to two winding ends. There’s no neutral. This setup makes the line voltage equal to the winding (phase) voltage, and the line current is √3 times the phase current.

In a wye (star) connection, one end of each winding is tied together at a common neutral point, and the other ends go to the three lines. This provides a neutral path for grounding and single-phase loads. Here, the line voltage is √3 times the winding voltage, and the line current equals the winding current.

These two configurations are the standard types used to adapt voltage and current for different supplies and loads, which is why they’re the correct answer. Other descriptions like series/parallel or high/low don’t describe the common winding connections used in three-phase systems.
