What is a pole-top transformer?

A pole-top transformer is specifically designed to be mounted on utility poles for the purpose of reducing high voltage electricity to a safer, lower voltage that can be distributed to homes and businesses. This transformation process is crucial for making electricity usable for end consumers since transmission lines often operate at very high voltages to be efficient over long distances. By reducing the voltage at the pole, the pole-top transformer ensures that the electricity delivered to the community is at a level that can be safely utilized by residential and commercial electrical systems.

The answer emphasizes the key role of these transformers in voltage regulation and distribution, highlighting their essential function in the electrical power delivery system. While other options may touch on various electrical components and their functions, they do not accurately describe the specific characteristics and purpose of a pole-top transformer.
