Do switchyards typically contain power transformers?

• A. Sometimes
• B. False
• C. Never
• D. True

Answer: (B)

Switchyards are the high-voltage switching points where transmission lines are connected, routed, and protected. They’re designed to control the path of power and isolate faults, using equipment like breakers, disconnect switches, and busbars. They don’t change voltage levels. Power transformers, which step voltage up or down, belong in substations where voltage transformation is performed and where cooling and clearance requirements are managed. Because transforming voltage adds hardware and safety considerations that are outside the switchyard’s primary role, switchyards typically do not contain power transformers.
