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.
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.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.
4.It has perfect protection function of counter potential.
5.With the function of automatic discharge and discharge indication, reduce the wrong operation, ensure the safety of equipment and personnel.
6.Can permanently store 500 sets of test data and can also use a usb flash drive to store data.
7.Wide applicable temperature, high precision, shockproof, anti-interference and easy to carry.
