What are the technical considerations for transformers oil filled?

When considering oil-filled transformers, key technical aspects include the type of insulating oil used, which must have high dielectric strength and thermal stability. The design must ensure proper cooling through oil circulation, and the transformer must be equipped with adequate ventilation to prevent pressure buildup. Additionally, monitoring for moisture content and contaminants in the oil is crucial for maintaining performance and longevity. Compliance with environmental regulations regarding oil leakage is also essential.
