Thank you all for your information,
This trafo has to run in overload (max 10 %) during e faw weeks,now I have confirmation about the idees that I had
myself (alarmsetting at 85°C)
Thank you all and greetings from Belgium

What is a maximum practicle value (°C) for an oil-trafo
5 MVA (natural cooling) at full load.
The transfomer has never been at full load for 35 years.
The values given by different manufactors seems to me very
low.
Thanks, JETO - Belgium
