Hello to all,
I was at a small farm house that had a single phase supply. The meter had to be moved because the customer was turning the room into a bathroom. The electricity was supplied by two overhead lines horizontally parrallel to each other on poles. There was a transformer on the pole. The supply was pme at the house. Could someone please explain how this works? Could it be two phases at 11000V going directly into a transformer and distributed to a house or would it have to be much less, say 3000Vs? How would the transformer windings be set up? With two phases coming in how do we get the return path (or neutral cable) to feed the house? Is it likely that the consumers side of the transformer is connected to earth at the pole?
I understand about delta : star transformers with three phases coming in, creating a 0 point from which the neutral can be taken from. Is it the same with just two phases coming in?
Any help is seriously appreciated. Trying to nail this is proving to be very tricky.
