Which term is an interchangeable name for area substation cubicles?

• A. Metering Cubicles
• B. Protection Relay
• C. Distribution Transformer
• D. Switchgear Cubicles

Answer: (D)

The concept being tested is what you call the enclosure that houses the switching equipment used to control and protect the substation network. Area substation cubicles are modular enclosures, and the ones that contain the switching gear—circuit breakers, disconnects, and related protective devices—are referred to as switchgear cubicles. That term emphasizes the primary contents and function of the enclosure. Metering cubicles are meant for measuring energy, protection relays are specific devices inside, and a distribution transformer is the equipment being protected or controlled, not the cubicle type itself. So the interchangeable name for area substation cubicles is switchgear cubicles.
