Application Scenarios
The DC resistance value measured by the DC Winding Resistance Tester can reflect the welding quality of the winding joints, whether there is an inter-turn short circuit in the winding, whether the contact of each position of the voltage tap changer is good, whether the actual position of the tap changer matches the indicated position, and can also reflect whether there is a break in the lead wire or whether there is a broken strand in the multi-strand wire.

It offers Chinese/English switching to suit different users. Voice prompts are available throughout the test, with both male and female voices selectable.
It has excellent safety features. After the test, a discharge audible alarm is triggered, and the screen also displays a notification, ensuring operator safety.
It offers six current levels, selectable according to the on-site testing conditions. An automatic mode is also available, allowing operation without prior setup.
FAQ
Q: What is a DC Winding Resistance Tester used for?
A: It is mainly used to test finished and semi-finished transformers, checking parameters such as the welding quality of winding joints and the presence of short circuits between winding turns, to see if the transformer meets the applicable standards.
Q: What parameters does a transformer DC resistance tester have?
A: Depending on the capacity of the transformer being tested, different current parameters can be selected, such as 10A, 20A, 40A, 50A, and 100A.
Q: What are the advantages of a three-phase transformer DC resistance tester?
A: A three-phase transformer DC resistance tester can test all three phases (A, B, C) of the transformer simultaneously, making testing more convenient and faster than single-phase testing.
