Description
Overview
GAOTek power frequency transmission line tester along with the development of the power grid and line corridors land tensions, with how to set up more and more prevalent, transmission line coupling between the increasingly close, interference when transmission lineman frequency parameter test is more and more strong, serious impact on the accuracy of the test, and test the safety of the equipment, in order to solve this problem, we developed a new generation of transmission line pilot frequency parameter test system, integrated frequency testing power supply, precision measuring module. high-speed digital processing chip and the unique national patent technology induced voltage circuit resistance; it can effectively eliminate the influence of strong interference. ensure the safety of instruments and equipment
