What is the function of a transformer oil conservator?

The function of a transformer oil conservator is to maintain the oil level in the transformer tank, compensating for oil expansion and contraction due to temperature changes. It allows for the safe storage of excess oil while preventing moisture ingress and oxidation. The conservator is typically connected to the transformer tank via a pipe and is equipped with a breather to ensure that the oil remains in optimal condition, thus enhancing the transformer’s reliability and lifespan.
