What is a location where transmission lines terminate and voltages are adjusted using transformers?

• A. Power station
• B. Substation
• C. Relay station
• D. Distribution center

Answer: (B)

A substation is a key component in the electrical grid where transmission lines terminate. It serves several critical functions, one of which is to house transformers that adjust voltage levels for safe and efficient distribution of electricity. These transformers can either step up the voltage for transmission over long distances or step it down for distribution to homes and businesses. Substations also play an essential role in maintaining the reliability and stability of the electrical system, as they can manage the load and redirect electricity as needed. They often include other equipment such as circuit breakers and switches to facilitate control over the electrical flow, enhancing safety and system operation. The context of this question highlights the importance of substations in the electrical infrastructure, setting them apart from other facilities like power stations, which generate electricity, relay stations, which can manage signal or control but do not perform voltage adjustments in the same manner, and distribution centers, which focus on the final delivery of electricity to consumers rather than voltage transformation.
