SUMMARY
The discussion clarifies why phases do not short out in three-phase delta transformers despite being interconnected. The transformer winding does not create a short circuit; instead, it transforms load impedance based on the turns ratio (N2). In the absence of a secondary load, the primary winding behaves as a high impedance, resulting in minimal current flow. Additionally, the vector sum of two phases equals the third, maintaining system stability. Properly labeled transformer nameplates include winding diagrams that illustrate these angular relationships.
