I. LYXC3000 Line parameter tester  overview
LYXC3000 Line parameter tester is a high-precision testing instrument for testing power frequency parameters of various high-voltage transmission lines ( overhead, cable and overhead cable hybrid ) on site. It is applicable to the occasions where the generator is used for power supply detection after all power outages.
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 parameters of power transmission lines, which integrates frequency conversion testing power supply, precision measurement module, high-speed digital processing chip and unique national patent technology anti-induced voltage circuit. Effectively eliminates the influence of strong interference, ensures the safety of instruments and equipment, and can measure power frequency parameters of transmission lines extremely conveniently, quickly and accurately.
