This transformer DC resistance tester is specially designed for the temperature rise measurement of three-core five-column large-scale transformers. The charging and measurement speed is fast, which can meet the time requirements of the transformer temperature rise test is no longer a problem.
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 single-chip microcomputer, which automatically completes functions such as self-checking, data processing, and display, and has the functions of automatic discharge and discharge indication. The instrument has high test accuracy and simple operation, and can realize fast measurement of transformer direct resistance.
