What is a pad-mounted transformer?

A pad-mounted transformer is specifically designed to be installed on a concrete pad, which provides a stable base for the equipment. This type of transformer is commonly utilized in underground distribution systems where the transformer needs to be placed at ground level for easy access and maintenance. Its design allows for efficient electrical distribution in residential and commercial areas, facilitating the connection of underground lines and helping to prevent potential hazards associated with overhead wiring.

By mounting the transformer on a concrete pad, it also minimizes the risk of flooding and damage from environmental factors, which is important for maintaining reliable power distribution. The other options describe different types of transformers or installations, but do not pertain to the specific characteristics and applications of pad-mounted transformers.
