The Purpose of Measuring DC Resistance

The Purpose of Measuring DC Resistance

The main purpose of measuring DC resistance is to check the following aspects of the transformer:1. Whether the welding or mechanical connection at the winding wire connection is good, and whether there are any welding or connection defects.2. Whether the connection between the lead and the sleeve,
