With the development of power grid and the shortage of land for line corridors, it is more and more common to erect multiple circuits on the same pole. The coupling between power transmission lines is getting closer and closer. The interference is getting stronger and stronger during the power frequency parameter testing of power transmission lines, which seriously affects the accuracy of testing and the safety of testing instruments and equipment. To solve this problem, we have developed a new generation of testing system for different frequency.
