The transformer DC resistance is a required test item for the factory test, installation and handover test of semi-finished products and finished products in transformer manufacturing, as well as the preventive test of power department. It can effectively find the manufacturing defects such as material selection, welding, loose connection parts, missing stocks and broken wires of transformer coils and the hidden trouble after operation.

Feature/Function

1. All DC resistance data of high and low voltage winding can be measured with one wire connection.

2. Three-phase simultaneous measurement with magnetic method, the speed is faster and the remanence hazard is greatly reduced..

3. It has perfect protection function of counter potential.

4. Display and print all the test data of transformer high and low voltage winding, and calculate the three-phase unbalance rate automatically, and print the resistance value converted to the rated temperature.
