What does the NEMA standard symbol for a set of transformer windings show?

• A. Primary windings
• B. Secondary windings
• C. Both primary and secondary windings
• D. Ground connection

Answer: (C)

The NEMA standard symbol for a set of transformer windings indicates both primary and secondary windings. This symbol is essential for understanding transformer connections, as it visually represents how the windings are arranged and interact within the transformer. The symbol typically shows a clear differentiation between the primary winding, which is connected to the input power source, and the secondary winding, which delivers the transformed voltage to the load. By depicting both windings together, it allows for a comprehensive understanding of the transformer’s operation, including how energy is transferred and transformed between the primary and secondary sides. This understanding is crucial for properly applying transformer theory in electrical installations and ensuring safe and efficient operation of electrical systems.
