This session will focus on offline testing techniques for transformers and the knowledge these methods can bring about asset condition. This information can be used as part of your ongoing condition assessment programme or to diagnose underlying issues detected through other means such as online monitoring. During this webinar we’ll consider real-world examples of testing, diagnosis and data management. LEARN MOREFind out more »
The TRF-250 is Vanguard’s fourth generation transformer turns ratio tester. This latest design provides a higher turns-ratio test voltage of 250Vac, provides a wireless Bluetooth PC interface, and features a 44-key “QWERTY”-style membrane keyboard. All these features greatly improve the accuracy of the turns ratio readings, ease of operation, and reliability. The TRF-250 determines the turns ratio of the transformer under test using the IEEE C57.12.90 measurement method, within the range of 0.8 to 50,000 to 1. Transformer turns ratio,…Find out more »
