What is the DC resistance of a transformer? What are the methods of measuring DC resistance?

The DC resistance of the transformer refers to the DC resistance value of each phase winding. The purpose of measuring the DC resistance of the transformer is to check the welding quality of the winding joints and whether there is a short circuit between the winding turns; to check whether the conta
