The importance of the tank expansion coefficient on the internal tank pressure was first realized in 1959, during experiments on oil-filled rectangular transformer tanks subjected to sudden discharges of nitrogen, and was simultaneously confirmed by numerical studies [6,7].

To Stop Transformers From Exploding, Make Their Tanks

When you have an arc inside the transformer, it heats up the oil and the oil burns to create a gas, which causes high pressure, explains Samuel Brodeur, a senior mechanical engineer at the angola transformer tank oil technologyTransformer conservator tanks T&D Guardian Articles USAThe transformer conservator tank acts similarly to the overflow tank on the radiator of a car. As the transformer load cycles, so does the oil temperature. All fluids, including transformer oil, change volume when the temperature changes. Common transformer oil Welding on an oil-filled transformer T&D Guardian angola transformer tank oil technologyA conservator tank design is completely full of oil, but the external air is separated from the oil by a rubber bladder. Welding on a transformer with this type of oil preservation system is less risky because there is no gas space. Use caution, though, because you are still using a lot of heat with very flammable oil.

Why Conservator Used in Transformer? Electrical Concepts

Jan 08, 2019A conservator tank of transformer provides adequate space to this expanded transformer oil. It also acts as a reservoir for transformer insulating oil. When volume of transformer insulating oil increases due to load and ambient temperature, the vacant space above the oil level inside the conservator is partially occupied by the expanded oil.Why Conservator Used in Transformer?
