What is Transformer Oil?
Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulation properties.
What is Transformer Oil Tester?
Transformer oil tester is a device that measures one or more of its parameters to determine the current condition of an oil.
Why is Transformer Oil Test Necessary?
Transformer oil testing consists of measuring the breakdown voltage and other physical and chemical properties of oil samples using portable test equipment in a laboratory or in the field. Transformer oil, a type of insulating and cooling oil used in transformers and other electrical equipment, needs to be tested periodically to ensure it is fit for purpose. This is because it tends to degrade over time. Test sequences and procedures are defined by various international standards. Transformer oil (insulating oil) of voltage transformers and current transformers fulfills the purpose of insulating as well as cooling. Therefore, the dielectric quality of the transformer oil is essential to assure the operation of a transformer. Since transformer oil deteriorates due to aging and moisture ingress, transformer oil should be tested periodically depending on economic, transformer duty and other factors. Through testing, the life of transformers can be increased significantly, delaying the new investment of new transformer assets.
