TKZZ-20S Three-channel 20A DC Resistance Tester

The DC resistance of a transformer is an item that needs to be measured in the semi-finished product, finished product factory test, installation, handover test and preventive test of the power sector in the manufacture of transformers, which can effectively find the transformer line

Manufacturing defects such as material selection, welding, loose joints, missing stocks, and wire breakage of the ring, and hidden dangers after operation. In order to meet the needs of rapid measurement of transformer DC resistance, our company has developed a

TKZZ-20S three-channel DC resistance tester connected to the winding. The TKZZ-20S three-channel DC resistance tester realizes three simultaneous power-on, independent current sampling, voltage sampling, and simultaneous measurement

It also displays the three-phase resistance value and the three-phase unbalance rate function, which greatly shortens the test time of the transformer DC resistance and solves the problem of long time-consuming DC resistance test of each tap winding of the power transformer.

The time required is only 1/3 of the traditional method.
