Introduction to Oil Conservator In Transformer
An oil conservator, also known as an oil expansion tank, is an essential component in oil – filled transformers. Its main function is to provide a space for the expansion and contraction of the transformer oil due to temperature changes. As the temperature of the transformer rises during operation, the volume of the oil increases. The oil conservator allows the excess oil to flow into it. Conversely, when the temperature drops, the oil flows back from the conservator to the transformer tank. This helps to maintain a proper oil level in the transformer and also prevents air from entering the main tank, which could cause oxidation and degradation of the oil and insulation materials. Additionally, it serves as a reservoir for filtering and testing the transformer oil, ensuring the long – term reliable operation of the transformer. Oil Conservator In Transformer
