Transformers Help To Move Electricity Efficiently Over Long
Distances

To solve the problem of sending electricity over long distances, William Stanley developed a
device called a transformer. The transformer allowed electricity to be efficiently transmitted over
long distances. This increased delivery range made it possible to supply electricity to homes and
businesses located far from the electric generating plant.
The electricity produced by a generator travels along cables to a transformer, which changes
electricity from low voltage to high voltage. Electricity can be moved long distances more
efficiently using high voltage. Transmission lines are used to carry the electricity to a substation.
Substations have transformers that change the high voltage electricity into lower voltage
electricity. From the substation, distribution lines carry the electricity to homes, offices, and
factories, which require low voltage electricity.
