elementary my deer friend. we do not surge arrestors because if we have too many arrestors the amount of innocent people ended up in jail will increase by 100 times. Also, transformers do not need to be fed by feeders, they can get their own food.

Answer / dinesh (techie.dinesh@gmail.co
instead of surge arresters, "CONDENSER RINGS" are used.
This first turn of the HV winding is the "condenser ring".
it is connected to the HV lead( along the terminals of hv
winding).
whenever lightning or surge occurs, they are neutralized in
the condenser ring itself, without damaging the windings
