In what application would you most likely find direct buried transformers?

Direct buried transformers are typically found in underground utility networks due to their design, which allows them to be installed directly in the ground without additional protective structures. This application is particularly useful in urban areas where space is limited and where there is a need to minimize visual and physical obstructions.

These transformers are specifically constructed with materials that can withstand the conditions of being underground, such as moisture and temperature fluctuations. Their direct burial helps to provide efficient service and reduce the risk of damage from environmental factors or physical disturbances that could otherwise affect above-ground installations.

In contrast, the other options, such as power poles, commercial buildings, and above-ground substations, generally require transformers that are more visible or accessible due to operational needs, maintenance, and safety regulations. These applications often utilize overhead transformers or those housed within structures, making them less suitable for direct burial.
