Transformer DC resistance testing is a critical procedure during factory assessments, installations, overhauls, tap changer modifications, handover evaluations, and routine preventive checks by power departments. This test serves multiple purposes:

It evaluates the quality of soldering at the winding joints.
It identifies potential short circuits between turns in the winding.
It verifies the integrity of contacts at each setting of the voltage tap changer.
It ensures that the tap changer’s actual position aligns with its indicated position.
It detects any disconnections in the outgoing lines.
It identifies any instances of broken strands, especially in windings made of multiple strands.
