Why Conservator Used in Transformer? | Electrical Concepts

Jan 08, 2019 · A 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.Transformer 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.
