DC resistance measurement is a must-test item in transformer manufacturing for semi-finished products, finished products, factory test, installation, handover test, and preventive test of the power department. It can effectively find manufacturing defects such as material selection, welding, loose connection parts, lack of strands, and wire breakage of transformer coils. And hidden dangers after operation.
In order to meet the needs of transformer DC resistance measurement, the company has recently developed a tool-based handheld DC resistance tester using its own technological advantages. This instrument adopts brand-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 microcomputer, which automatically completes the functions of self-inspection, data processing, and display. It also has functions such as automatic discharge and discharge sound alarm indication. The instrument has high measurement accuracy and simple operation, which can realize rapid measurement of transformer DC resistance.
