Answer :

The main function of conservator tank of transformer is to provide adequate space for expansion of oil inside the transformer.

Function of Conservator Tank of a Transformer

When transformer is loaded and when ambient temperature rises, the volume of oil inside transformer increases. A conservator tank of transformer provides adequate space to this expanded transformer oil. It also acts as a reservoir for transformer insulating oil.
