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 1926.57 - Ventilation.Occupational Safety and Health
