Which symbol indicates the same winding in a transformer rating?

The symbol that indicates the same winding in a transformer rating is the slant (/). In transformer notation, when two windings are connected in such a way that they have the same phase relationship and are considered to operate together, the slant is used to denote these similar windings.

This symbol effectively communicates that the windings are interconnected in a way that will maintain their phase alignment, which is crucial for the correct operation of the transformer. Properly identifying these connections ensures that the transformer functions as intended, without issues related to phase mismatches, which can lead to inefficiencies or even damage.

While the other symbols mentioned may have their respective uses in electrical notation or systems, they do not convey the concept of identical winding configurations as clearly as the slant does. The hyphen typically indicates a difference or separation, the times symbol is often used for multiplication, and letters usually refer to the types of windings or specific characteristics related to them. Hence, using the slant is the standard practice in transformer rating to indicate similar windings connecting in phase.
