The lesson discusses aspects of unused mineral oil after its receipt by the end-user, such as storage, sampling, testing before and after filling into an equipment and the limits to parameters. The lesson also deals with the process and precautions for filling oil into a transformer.

Join us and learn how the oil should be stored and handled, about testing different oils for compatibility in case a new oil of a different vendor is used for topping up in an equipment and, finally, about the limits for oil parameters after filling and before energizing a transformer.
