Auto Transformer modeling !
Auto Transformer modeling !
(OP)
I would like to have some idea about auto transformers. Perticularly, input voltage 220 kV, output voltage 33 kV and there is 132 kV tapping as well. This is not a three winding transformer. There are few this type of transformes in our transmision network. A name of a text book or some discription for modeling and opertion principle is very much appriciated.
