Unstable result can cause wrong decision

Even if unexpected winding resistance values are obtained, it does not necessarily indicate a transformer defect. Many factors influence results deviation, and they all have to be considered before taking a decision. The most important factor to be considered when analyzing winding resistance results is a stabilization process.

Read the DV Power Application Note and find out theory background, how to monitor the stabilization process, what are the consequences of unstable results, and DV Power experts recommendations for this test.
