Power on 35kv provided by 2 Systems with 220/35kv transformers "YNynd(d1)" configurations and few 11KV Generators with 11/35KV transformers marked "Dyn11" on single line diagram, but showing that "D" from 11KV and "yn" from 35KV sides. If "Dyn" marks for transformer, it is usually mean that "D" from high side transformer and "yn" from low side. This is my question. Please tell me, what is right for my project: "Dyn11", "YNd1" or "YNd11" and what rotation will be for the generators-ACB or ABC?
