How does a dry type transformer compare to an oil-filled transformer?

When comparing dry type transformers to oil-filled transformers, several key differences emerge that can influence selection based on application requirements. Dry type transformers are insulated with air and use solid materials for cooling, making them suitable for indoor environments as they pose minimal fire risk and eliminate the need for oil handling and storage. In contrast, oil-filled transformers utilize mineral oil for insulation and cooling, providing superior heat dissipation and allowing for higher power capacity in smaller designs, making them ideal for outdoor applications and large installations. However, oil-filled transformers require more maintenance due to potential leaks and environmental concerns. Ultimately, the choice between a dry type transformer vs oil-filled transformer hinges on factors such as installation site, capacity needs, safety regulations, and maintenance considerations.
