FeedbackDESIGN OF TRANSFORMERTotal volume ii.Total weight iii.Total cost atmospheric hazards,the transformer is placed in a steel tank filled with oil.The oil conducts the heat from core and coil to the tank walls.From the tank walls the heat goes dissipated to surrounding atmosphere due to radiation and convection.24.

How is an oil filled transformer filled with nitrogen?How is an oil filled transformer filled with nitrogen?In a nitrogen blanket design,the tank is filled with oil to about 90% of the height of the tank.The top 10% is filled with nitrogen gas to allow for thermal expansion of the oil.As a precaution,do not assume that the gas is pure nitrogen.It very well could contain some oxygen or combustible gasses.Welding on an oil-filled transformer TD Guardian Articles USA What causes a transformer tank to go over 50kV?What causes a transformer tank to go over 50kV?Phase to phase and earth faults are virtually impossible.Lightning takes out a lot of pole transformers causing them to explode oil over an area greater than any bund could catch.Again,the root cause is now well understood.A lightning induced flash over on the HV bushing causes the transformer tank to rise to more than 50kV.Bunding Oil Filled Transformers To Bund or Not to Bund
