Transformers are intalled between power stations and the grid and between different networks to raise or lower the voltage when required.

Transforming stations usually contain several transformers and are located where several lines meet. They provide a means of regulating the flow of power in response to demand or problems on a line, a transformer or switchgear. Automatic systems make an important contribution.
