The transformer windings are amongst the main components to maintain to ensure proper functionality and reliability of the system. Among the most important tests to assess the transformer winding’s condition are Transformer Turns Ratio (TTR), Windings Resistance (WR) and Excitation Current measurements. There is a strong correlation between these three measurements, as in conjunction they can detect windings related issues, such as improper number of turns, turn-to-turn insulation failure, internal connection problems -- including those to the tap changers (if installed) -- as well as shorted laminations in the core, ground faults, residual magnetism, and core structure deficiencies.
Join us for this Best Practices Seminar to learn more about the theory of these important diagnostic tools, as well as the tools and analysis criteria that can help you assess the condition of the transformer windings.
