Hi everyone,
Does anyone know how the transformers are connected in power transmission and distribution systems? I mean star-delta, delta-star, delta-delta etc
In Cyprus after the alternator there is the step-up transformer (11KV/132KV), then the HV step down transformer (132KV/11KV) and finally additional LV transformers for distribution (11KV/400V)
I believe that the secondary of the LV transformer is star connected in order to provide neutral to feeders, but what about the primary? Also what about the rest of the transformers?
Thanks
