Transformer Parallel Operations



Transformer Parallel Operations..

Answer / saadi

Can i connect Dyn11yn11 parallel with Dy11y11 – DeltaHV side Dual LV winding star connected? I have 7 dry transformers with Dyn11yn11 configuration but we didn’t connect neutral with the transformer. Now i am thinking to order a new oil transformer of Dy11y11 configuration. According to my understanding, there won’t be any problem because the difference is just having neutral connection out or not?
