Product Overview
The DC resistance of the transformer windings must be measured
Measuring DC resistance of transformer windings is a very important test item. Its purpose is to:
1. Check the welding quality of wires and leads inside the winding;
2. Check whether all positions of tap switch are in good contact;
3. Check whether the winding or the lead wire is broken;
4. Check the correctness of parallel branches, whether there is one or several wire breaks in the winding made by several parallel wires;
5. Check whether there is a short circuit between layers and turns.
