What are the advantages of dry type transformers versus oil-filled ones?

Dry type transformers vs oil type transformers each have their own advantages that cater to different applications. One of the primary benefits of dry type transformers is their lower risk of fire hazards, as they do not use flammable oil as a coolant. Additionally, they require less maintenance because there is no need to monitor oil levels or manage oil leaks, which are critical considerations for oil type transformers. Dry type transformers are more environmentally friendly due to the absence of oil, eliminating the risks of oil spills and contamination. They also have a more compact design, making them ideal for urban settings where space is limited. Furthermore, dry type transformers offer superior performance in terms of resistance to moisture and dust, thus making them suitable for harsh environments. However, oil type transformers are known for their better cooling efficiency and can handle higher loads, making them beneficial in industrial applications. Therefore, the choice between dry type transformers vs oil type transformers ultimately depends on the specific requirements of the application, including safety, maintenance, environmental concerns, and operational performance.
