Transformer oil, a type of insulating and cooling oil used in transformers and other electrical equipment, needs to be tested periodically to ensure that it is still fit for purpose. The transformer oil insulation oil of voltage- and current-transformers fulfills the purpose of insulating as well as cooling.
Ganegala and General Manager Eng. Some of them are even battery-powered and come with accessories. As transformer oil deteriorates through aging and moisture ingress, transformer oil should, depending on economics, transformer duty and other factors, be tested periodically.
To assess the insulating property of dielectric transformer oil, a sample of the transformer oil is taken and its breakdown voltage is measured. This article needs additional citations 601156 verification.
