TECHTALK: Leakers… What a Mess! Cost Effective Methods for Repairing Transformer and Circuit Breaker Oil Leaks


A non-invasive repair technique performed on oil filled transformers and circuit breakers whereby oil leaks can be repaired with apparatus still alive and in service carrying load. Identify and repair oil leaks before they become reportable oil spills. Repairs can be made without draining oil and disassembly of the transformer or CB, reducing your repair time to hours vs. the days required for major regasketing. This method can also apply to SF6 gas leaks too.
