While the operating principles of transformers have remained the same for nearly a century, the challenges of maintaining and testing transformers have evolved along with transformer design and construction. Modern transformers are designed to closer tolerances than ever before. Proper testing is essential for evaluating the condition of a transformer. This predictive data will guide maintenance activities and help prevent catastrophic failure that damages downstream equipment and endangers personnel.
