volume adjustment upon changes of coolant temperature caused by load or ambient temperature alterations. Suitable guides are provided on the tank bottom for guiding the active part into the tank, as well to prevent displacement during shipping and transformer operation.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. Common transformer oil changes volume Transformer Oil level in conservator tank- practical israel transformer tank building volumeThere should be some oil in the conservator tank for safe operation. As the transformer oil has a high expansion and compression value with temperature, with high temperature the oil volume increases and low temperature the oil volume decreases significantly.
