Szukana fraza: [Abstrakt = "The article describes the problems of moisture in the insulation system of the power transformer. The causes and effects of moisture presence in insulating materials are characterized. The methods of drying transformer insulation are also presented. The problems related to the effects of high moisture in the insulation system and the risk resulting from the need for its ad hoc \(quick\) drying can be avoided by using a noninvasive method of continuous drying of the solid insulation with high hygroscopic sorbents. The article compared the hygroscopicity of selected sorbents\: molecular sieves 3A, 5A and 13X, alumina and silica gel. Moreover, the results of drying mineral oil by means of 13X molecular sieve are presented."]
