Dec 16, 2019 · Area of transformer pad = 8 x 10 = 80 square feet. Total area = 220 + 80 = 300 square feet. To fit within the fence line in a symmetrical containment area, choose a width of 13 feet (6.5 feet in each direction). A length of 24 feet would provide a total area of 312 square feet to meet our oil containment needs.Specific weight of transformer oil - GlobeCoreIn practice the temperature difference may be more than 100ºC, so the volume of the expansion tank should be 9-10% of oil volume. There is also such parameter is specific gravity of transformer oil. It must be relatively low, since it allows the sediment to separate more easily and to settle better in the transformer, not hindering the circulation of the insulation fluid.Transformer conservator tanks | T&D Guardian Articles namibia transformer tank oil volumeThe 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
There 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.
