What is an electricity substation? | National Grid Group
Substations contain the specialist equipment that allows the voltage of electricity to be transformed (or ''switched''). The voltage is stepped up or down through pieces of equipment called transformers, which sit within a substation''s site. Transformers are electrical devices that transfer electrical energy by means of a changing magnetic ...
