Mitigation of transformer Oil Leakage

Mitigation of transformer Oil Leakage

Mitigation of transformer Oil Leakage

(OP)
I work for Eskom Electricity Utility in South Africa. We experience oil leaks on most of our distribution transformers. The leaks are on the gasket between the transformer tank and the bushings. The seals wear and tear over time. I know that there are oil leaks arrest putties and sticks to mitigate the oil leaks. I have questions with regards to the leak arrests:

i. What is the success rate of transformer oil leak arrestor

ii. The transformer seals (rubber material) can wear and tear when they come into contact with water and exposure to sunlight. Are the oil leak arrestors (e.g. putties & sticks) immune to the environmental effects?

Poor workmanship can contribute to the oil leaks on the gasket between the transformer tank and bushings. Are there any other mitigating measures to transformer oil leaks.

Your assistance will be highly appreciated.

Kind Regards
