What are multiple-tapped windings?

Multiple-tapped windings are characterized by having several connections that allow for multiple voltage outputs or configurations within the same winding. This design enables flexibility in voltage selection by adjusting where the load is connected along the length of the winding. Essentially, each tap corresponds to a different point in the winding, offering varied voltage levels while maintaining the same core structure.

This feature is particularly useful in transformers and electrical equipment where different operational voltages are required without the need for multiple separate windings. It enhances efficiency and versatility in applications where different voltage needs might arise.

The other options do not align with the definition of multiple-tapped windings. Windings that lack lead wires do not allow for any connection, while very short windings and single lead wires refer to different configurations that do not relate to the multi-tap concept.
