What is a primary advantage of using dry type transformers over oil-filled types?

A primary advantage of using dry type transformers over oil-filled types is the reduced environmental hazards. Dry type transformers do not contain flammable liquids like oil, which can pose environmental risks in case of leaks or spills. This characteristic makes them safer to operate in populated areas or locations where environmental protection is a priority. Furthermore, dry type transformers often require less maintenance compared to their oil-filled counterparts, leading to a lower risk of accidental environmental contamination. The absence of oil greatly diminishes concerns related to fire hazards and toxic exposure, highlighting their suitability for various applications where safety and environmental impact are key considerations.
