Retro-filling with gas-to-liquids (GTL) oil might cause problems with leaks in transformers previously filled with naphthenic oil. That is what Nynas scientists found when conducting an investigative study following customer reports about transformer leaks.

“We were made aware of reports from customers that they had experienced significant leaks when retro-filling transformers with GTL,” says Robert Fairholm, Development Engineer at Nynas Naphthenics section for Electrical Industry Technical Development and Market Support.

Despite assurances from the manufacturer that the compatibility between GTL fluids and typical sealants used in transformers was not an issue, Nynas decided to dig a little deeper.
