Introduction about the Transformer DC resistance tester

Check the welding quality of the winding joints and whether the winding have inter-turn short circuits. You can check whether the contact of each position of the voltage tap switch is good, whether the actual position of the tap changer matches the indicated position, whether the lead wire is broken, and the multi-stranded wire is wound in parallel. Whether there is stock breakage, etc.
