What is a transformer turns ratio tester used for?

A transformer turns ratio tester is an essential device used for evaluating the turns ratio of transformers, which is crucial for assessing their operational integrity. It measures the ratio of the primary winding voltage to the secondary winding voltage and can identify issues like improper connections or faults within the transformer. Using this tester helps in preventive maintenance, ensuring transformers operate efficiently and safely. Regular testing with a transformer turns ratio tester can help in diagnosing potential problems before they lead to transformer failures, thus enhancing reliability in industrial applications. This equipment is vital in the broader context of diagnostic tools like the transformer megger test, ensuring the longevity and optimal performance of transformers and associated electrical equipment.
