Professional Answer: A typical substation houses a variety of specialized equipment to perform its functions safely and efficiently. Key components include:

• Transformers: The most vital component, used to step up or step down voltage.

• Switchgear and Circuit Breakers: Used for switching, protection, and isolating circuits during faults or maintenance.

• Insulators: Provide electrical isolation for high-voltage conductors.

• Busbars: These are thick conductors that carry electricity from one part of the substation to another.

• Surge Arresters: Protect equipment from lightning strikes and voltage surges.
