How Do Substations Work? — Practical Engineering

Substations are usually the only locations where extra-high voltage power lines get close to the ground, so safety is absolutely critical. The buswork running along the substation is protected from short-circuit by large insulators to avoid arcs to ground. Even the connections into each piece of equipment are done through a device …

Electrical substation

A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels. A substation may include transformers to change voltage levels …
