·The 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 by 0.07% per degree Celsius. How much oil is in a conservator transformer?How much oil is in a conservator transformer?Typically,when the conservator is filled to the 25°C mark,the tank is approximately 25-35% full.This leaves enough room for oil expansion when the transformer is operating at full load and the average oil temperature is in the range of 70-90°C.Transformer conservator tanks TD Guardian Articles Is the transformer low on oil in Arizona?Is the transformer low on oil in Arizona?The answer would be The transformer is low on oil if the transformer was loaded to 100% of nameplate rating during summer in Arizona.The average oil temperature must be considered when evaluating the liquid level.Typically,when the conservator is filled to the 25°C mark,the tank is approximately 25-35% full.Transformer conservator tanks TD Guardian Articles

What happens when the oil level falls in a transformer?What happens when the oil level falls in a transformer?When the oil level falls down in the conservator,the diaphragm deflects and the atmospheric air fills the vacant place.This air is sucked through silica gel breather which is connected to the top middle of conservator tank of transformer.(Here silica gel breather is not shown in the figure above)Conservator Tank of Transformer Electrical4U10.09.2013/20.01.2014 TECHNICAL SPECIFICATION FOR
