WRT-210A DC Resistance Tester
The DC resistance of transformer is a necessary test item for the factory test, installation, handover test and preventive test of semi-finished products and finished products in the manufacturing of transformer.
Description
The DC resistance of transformer is a necessary test item for the factory test, installation, handover test and preventive test of semi-finished products and finished products in the manufacturing of transformer. It can effectively find the manufacturing defects of transformer coil, such as material selection, welding, loose connection parts, lack of strands, broken wires and hidden dangers after operation. In order to meet the needs of fast measurement of transformer DC resistance, the company has developed 20A dual channel transformer DC resistance tester with its own technical advantages. The instrument adopts new power technology, which has the characteristics of small volume, light weight, large output current, dual channel measurement, real -time sampling, etc. The whole machine is controlled by single chip microcomputer, which can automatically complete self inspection, data processing, display, printing and other functions, and has automatic discharge and discharge indication functions. The instrument has the advantages of high accuracy and easy operation, which can realize the fast measurement of the direct resistance of the transformer.
