Transformer turns ratio (TTR) testing is one of several tests that are recommended in IEEE Std.C57.152.13 for field diagnostic testing of fluid-filled power transformers. This presentation briefly describes how transformers work and identifies information about transformers that are critical to performing transformer turns ratio testing. Watch as these principles are applied to perform an actual transformer turns ratio (TTR) test using a Raytech TR-Mark III testing kit.
