A method of tapping a high voltage transmission line for input into a power distribution substation is disclosed. The method comprises the steps of dividing the transmission line and attaching the conductors to the primaries of at least two transformers via a series connected first disconnect switch, second disconnect switch and circuit breaker. A bus interconnects the first disconnect switch and the second disconnect switch and the bus of the first transformer bay is connected to the bus of the second transformer bay using a circuit breaker. A system for the conversion of tapped high voltage electricity to medium voltage electricity is also disclosed.
