Product Description

Overview
1.DC resistance of motor transformer is a necessary test item for the delivery test, installation, handover test of semi-finished products and finished products in transformer manufacturing and the preventive test of power department. It can effectively find the manufacturing defects such as material selection, welding, loose connection parts, lack of strands, disconnection and other hidden dangers after operation of transformer coil. In order to meet the needs of rapid measurement of transformer DC resistance, the company has developed a DC resistance tester by using its own technical advantages. Transformer DC resistance tester this instrument adopts new power supply technology, which has the characteristics of small volume, light weight, large output current and automatic adjustment according to the size of load. The whole machine is sampled by dual chips with higher precision. It can automatically complete the functions of self inspection, data processing, display and printing, and has the functions of automatic discharge and discharge indication. The instrument has the advantages of high precision and simple operation, and can realize the rapid measurement of transformer DC resistance.
 
2.DC resistance measurement of winding is one of the routine tests of transformer. Its purpose is to check whether the connection or mechanical characteristics between windings, windings and leads are good, and whether the resistance between each phase winding is balanced, so as to ensure the safe operation of transformer.

3.32-bit ARM processing core is used to control the whole machine, automatically complete the functions of self calibration, steady current judgment, data processing and resistance value display, and can measure DC resistance of various types of transformers and transformers.
