RSR3310 Transformer Testing Equipment Three Channel DC Resistance Tester

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.When testing the winding with the neutral point in the star connection method, the instrument can adopt the method of three-phase simultaneous measurement to test the dc resistance of A0, B0 and C0 phases, which greatly saves the test time.

2.Display and print all the test data of high and low voltage winding of transformer, and calculate the three-phase unbalance rate automatically.

3.It has perfect protection function of counter potential.

4.With the function of automatic discharge and discharge indication, reduce the wrong operation, ensure the safety of equipment and personnel..

5.Can permanently store 500 sets of test data and can also use a usb flash drive to store data.
