Which device is used to perform switching operations on high voltage circuits to control power delivery?

• A. Generator
• B. Transformer
• C. Switches
• D. Circuit Breakers

Answer: (C)

Switching devices are the tools used to make or break a circuit so we can control how power flows on a high-voltage network. They are built to close or open connections, isolate sections for maintenance, or reconfigure feeders, all while handling the high voltages and currents involved. The key point is that their primary purpose is to control the delivery of power by switching the circuit on or off. A generator is the source of electrical energy; a transformer changes voltage levels. A circuit breaker does interrupt current to protect the system during faults, though it can perform switching as part of protection, its main role is rapid fault interruption rather than routine control of power delivery. Therefore, the device used to perform switching operations to control power delivery is the switch.
