True or False: Transformers with primary windings in a delta configuration can only be connected to delta 3-wire primary circuits.

True or False: Transformers with primary windings in a delta configuration can only be connected to delta 3-wire primary circuits.

• A. True
• B. False
• C. Sometimes
• D. Always

Answer: (B)

The assertion is false because transformers with primary windings in a delta configuration are versatile and can indeed connect to various configurations, not just delta 3-wire primary circuits. Delta-configured transformers can be connected to a variety of systems including wye configurations. The flexibility of delta connection allows transformers to be used in different applications, such as in industrial settings or in power distribution networks, which often include both delta and wye connections. This characteristic makes it possible to integrate delta-configured transformers into a wide range of electrical systems, enhancing their utility beyond just delta connections.
