DC resistance of transformer is a necessary test item for semi-finished products, finished products factory test, installation, handover test and preventive test of power department in transformer manufacturing. It can effectively find manufacturing defects such as material selection, welding, loosening of connection parts, lack of strands, broken wires and hidden dangers after operation of transformer coils. In order to meet the needs of fast measurement of transformer DC resistance, our company has developed this DC resistance tester by using its own technical advantages. The instrument adopts a new power supply technology and has the characteristics of small size, light weight and large output current. The whole machine is controlled by a single chip computer, which can automatically complete self-inspection, data processing, display and other functions. It has the functions of automatic discharge and discharge indication. The instrument has the advantages of high accuracy, simple operation and fast measurement of transformer direct resistance.

The instrument has high output current and light weight.

It has perfect protection circuit and strong reliability.

Vertical chassis structure, easy to operate on site.

It has sound discharge alarm, clear discharge indication, and reduces misoperation.
