Which equipment is not typically part of a switchyard?

• A. Regulation equipment
• B. Protection equipment
• C. Monitoring equipment
• D. Communication equipment

Answer: (A)

Switchyards are built to handle switching, protection, monitoring, and communication for control and safety. The equipment you’ll find includes switching devices like disconnectors and circuit breakers, protection gear such as relays and protective schemes, monitoring elements like sensors and meters, and communication gear for SCADA and remote control. Voltage regulation, however, is accomplished by devices associated with transformers and reactive support—primarily transformer tap changers and capacitor banks—not by standard switchyard equipment. Because regulation is provided by those other components rather than by the common switchyard gear, regulation equipment isn’t typically part of a switchyard. The remaining categories are integral to the switchyard’s function.
