1、 Product Introduction:
1MZC-HII(W)The DC resistance of transformers is a necessary test item for semi-finished and finished products in transformer manufacturing, factory testing, installation, handover testing, and preventive testing by the power department. It can effectively detect manufacturing defects such as material selection, welding, loose connection parts, missing strands, and broken wires of transformer coils, as well as hidden dangers after operation. In order to meet the needs of rapid measurement of transformer DC resistance, the instrument adopts a new power supply technology, which has the characteristics of small size, light weight, and large output current. The whole machine is controlled by a microcontroller, which automatically completes self checking, data processing, display and other functions, and has automatic discharge and discharge indication functions. The instrument has high testing accuracy, easy operation, and can achieve rapid measurement of transformer direct resistance.
2TheMZC-HII(W)DC resistance tester, output voltage40V， Current of 40A, specifically designed for large three core five column systemsTransformer temperature riseDesigned for measurement, with fast charging and measurement speed, it can meet the time requirements of transformer temperature rise test. With dual channel measurement, real-time sampling, and printing output, temperature rise test is no longer a difficult problem.
2、 Product features:
1. The instrument outputs high current and high voltage.
