What is the primary function of a switchyard?

• A. to route electricity to various circuits
• B. to generate electricity
• C. to store energy
• D. to convert DC to AC

Answer: (A)

The switchyard’s job is to route electricity to the right paths by connecting and disconnecting transmission lines with switching devices like circuit breakers and disconnect switches and by using busbars to hold those paths together. This setup sits at the substation interface between generations and the wider transmission network, letting operators direct power where it needs to go, reconfigure routes, and isolate lines for maintenance or when faults occur. It doesn’t generate energy, store energy, or convert voltages or currents—that happens in other parts of the system. So routing electricity to various circuits is what a switchyard is all about.
