The main function of conservator tank of transformer is to provide adequate space for expansion of oil inside the transformer. Function of Conservator Tank of a TransformerWhen transformer isCooling of Transformers OwlcationMay 29, 2018Oil in contact with the surface of windings and core gets heated up and moves towards the top and is replaced by the cool oil from the bottom. The heated oil transfers its heat to the transformer tank through convection and which in turn transfers the heat to the surrounding air by convection and radiation.

Field drying of transformer insulation T&D Guardian slovakia transformer tank oil technology

During the circulation period the oil is heated and passed through several filters to remove particulate matter. The oil also passes through a vacuum chamber where gas and moisture is removed. While maintaining vacuum on the transformer tank, the oil is then removed, exposing the solid insulation surface(s) to deep vacuum.Hermetically Sealed Oil Filled Transformer Archives - GBE SpAThe tightness of the tank is up to 0.5 Bar. This type of transformer is the most widely used in the world. In the hermetically sealed transformer, the oil does not come into contact with the air and its electrical properties are therefore not compromised, ensuring a long life span of the transformer.High-performance double-stage oil treatment plants slovakia transformer tank oil technologyIt is used for treating oil when the transformer or oil storage tank is lower than the vacuum oil treatment plant (with a horizontal difference of < 5 m), and enable oil treatment when the distance between the transformer or oil storage tank and the vacuum oil treatment plant is more than 15 m but less than 100 m.
