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. In order to meet the needs of rapid measurement of transformer dc resistance, the instrument adopts a new power supply technology, which is characterized by small size, light weight and large output current.The whole machine is controlled by single chip microcomputer, which can automatically complete the functions of self-check, data processing and display, and has the functions of automatic discharge and discharge indication.The instrument has high precision and easy operation, which can realize the rapid measurement of transformer resistance.
1. Large output current, high voltage.
2.Double channel measurement, simultaneously measuring two resistance values.
3.With perfect protection circuit, high reliability.
4.Horizontal structure, easy to operate in transformer factory.
5.With sound discharge alarm, discharge indication clear, reduce wrong operation.
