The winding resistance test of a transformer is a crucial assessment used to measure the resistance of the transformer windings. This test helps identify potential issues such as poor connections or winding failures that can lead to overheating and efficiency losses. During the test, a precise low-resistance ohmmeter or a dedicated low voltage resistance tester is typically used, which provides accurate readings by passing a known current through the winding and measuring the resulting voltage drop. This is an essential part of transformer testing equipment, as it ensures the integrity and functionality of the transformer. Regular winding resistance tests can help maintain the reliability and performance of transformers in industrial settings, supporting their longevity and operational efficiency.
