Why to use transformer DC resistance tester for test ？

The transformer DC resistance tester realizes the wide range resistance measurement, achieves the measurement effect and highly automatic measurement function. What is the purpose of using transformer DC resistance tester to measure DC resistance of transformer winding? Below is your detailed explanation!

1. Welding quality of wires and leads inside the winding;

2. Whether each position of the voltage tap changer contacts well and whether the actual position of the tap changer is consistent:

3. Whether the contact between transformer winding lead and current carrying conductor such as bushing is good;

4. Whether there is strand breakage in the winding of multi strand conductor

5. Whether the three-phase winding or circuit is balanced;

6. After the operation of transformer differential and gas protection, check the winding for turn to turn short circuit, winding and lead wire for fracture, etc. through measurement.
