What are the causes and effects of transformer oil leaks in power transformers?

The causes of transformer oil leaks in power transformers include aging seals, mechanical damage, and corrosion of components. These leaks can lead to a reduction in insulation effectiveness, increased risk of electrical faults, and environmental contamination. Additionally, transformer oil leaks can result in costly repairs and downtime, as well as potential regulatory penalties if the oil contaminates surrounding areas. Addressing these issues promptly is crucial for maintaining transformer reliability and safety.
