How does the winding voltage compare to the line voltage in a delta connection?

In a delta connection, the relationship between winding voltage and line voltage is that they are equal. This is because in a delta configuration, the voltage across each winding is synonymous with the voltage between the line terminals to which those windings are connected.

When analyzing a delta connection, it's essential to understand that each corner of the delta (where the windings connect) corresponds directly to the line voltage. Hence, if you measure the voltage across any single winding, it will equal the line voltage applied between the two lines connected to that winding.

Due to this equivalence, one can conclude that the winding voltage and the line voltage are indeed equal in a delta connection. This understanding is crucial for tasks involving phase and line voltage calculations in three-phase systems, particularly in the context of electrical engineering and equipment design.
