The use of a copper winding as a temperature sensor is not new. The traditional technique is to disconnect the ac power and the load and to quickly make the measurement using an ohmmeter. But the ...
Abstract: Accurate and effective diagnosis of transformer winding conditions is crucial for ensuring their safe and reliable operation. This paper proposes a transformer winding fault detection method ...
Abstract: Frequency response analysis (FRA) is a well-established technique to detect transformer winding deformation faults. Its diagnostic application is based on the principle that a transformer ...
