As transformer is the core equipment in power system, its long-term reliable operation is of high significance to the stability and reliability of the whole system.

The DC resistance of transformers must be tested for their delivery, installation and handover, regardless they’re semi-finished or finished transformers. It’s also indispensable in preventive tests for power sector. In this way, manufacturing defects like coil material, welding, loose connection, lack of strands and disconnection as well as hidden dangers after it’s put into use can be detected. This DC resistance tester is developed by taking full use of our technical advantages in order to meet the needs of fast measurement of transformer DC resistance. Boasting a large true color high-resolution LCD screen and adopting touch control and jog dial, it’s convenient to use on site. Featuring Chinese menu prompts, it’s simple and intuitive to operate. It’s fast to test with high accuracy and wide measurement range.
