In distribution networks, transformers are commonly found in which mounting configurations?

• A. Pole-mounted
• B. Pad-mounted
• C. Both Pole-mounted and Pad-mounted
• D. Underground Vaults

Answer: (C)

Transformers in distribution networks are commonly mounted in two main ways: on utility poles (pole-mounted) for overhead lines, and on concrete pads at ground level (pad-mounted) where feeders are underground or space constraints exist. Pole-mounted units are convenient along streets and rural or suburban overhead systems, while pad-mounted units are enclosed, weatherproof, and securely located near underground networks or in areas where an above-ground pole installation isn’t practical. Because both mounting styles are widely used to suit different network designs and environments, the best answer recognizes that transformers can be found in either configuration.
