The paper presents the results of the measurements of heat transfer coefficient of insulating liquids used in transformers. The coefficient describes an ability of the liquid to heat transport. On the basis of the coefficient, effectiveness of cooling system of electric power devices can be estimated. Following liquids were used for the measurements: mineral oil, synthetic ester and natural ester. It was assumed that surface heat load is about 2500 W·m -2 , which is equal the load ofdoi:10.1051/e3sconf/20171901026 fatcat:3itaf3ts6jb2vgagmgqjqrprw4
