WebHeat run test or temperature rise test is performed by applying a rated voltage and frequency to the primary side of the transformer under test, and a short-circuit winding in the secondary, for the aim of circulating rated current in the latter. The circulation of the rated current during the test makes the winding temperature rise with time. WebTransformer Testing The purpose of this article is to provide a list of the standard battery of tests performed on reconditioned and new transformers, while also providing an introductory explanation of the purpose and scope of the most common routine factory and diagnostic field tests.
