Product Description

Transformer's DC resistance is the transformer manufacture of semi manufactured goods, finished product testing, installation, handover test and power sector preventive test project, can effectively find the material selection, welding, connecting parts of the transformer, the loose, lack of shares, such as the existence of hidden trouble. In order to meet the needs of the rapid measurement of transformer DC resistance, the use of its own advantages of the development of the CT3220 series of DC resistance tester. 

This instrument adopts new power technology, which has the characteristics of small volume, light weight and large output current. The whole machine is controlled by single chip microcomputer, which can automatically complete the functions of self check, data processing, display and so on. The instrument has high accuracy, simple operation, and can realize the rapid measurement of transformer direct resistance.

(3 channes)l DC resistance tester, using dual power structure, the YN connection windings of the transformer, three-phase power, the measurement system using independent three channel current sampling, independent three channel voltage sampling, and display the three-phase resistance and three phase imbalance rate. Greatly shorten the working time, the power transformer to solve the power transformer winding DC resistance testing time-consuming problem, the time required is only the traditional method of 1/3.
