Oil leaks from transformer radiator fins are often caused by: - Corrosion - Faulty welds - Impact on the fins or steel tanks
Radiator fins are made from thin metal to help with heat transfer. This thinness makes them susceptible to corrosion from water ingress and separation, or external environmental corrosion.
Leaks from transformer radiator fins often feature slow drips, but large volumes of oil can be lost over time. This can be environmentally damaging.
To repair a transformer oil leak, you can: - Install a weir box to cover the leaking fin(s). - Take the transformer out of service, drain the oil, and remove the radiators.
