Product Introduction

Variable frequency line parameter tester, the instrument is integrated structure, built-in variable frequency power module, variable frequency voltage regulating output power. The frequency can be changed to 45Hz and 55Hz. Digital filtering technology is adopted to avoid the interference of power frequency electric field to the test, which fundamentally solves the problem of accurate measurement under the interference of strong electric field. At the same time, it is applicable to the occasion of power supply detection with generator after all power failure.

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, and measure the power frequency parameters of transmission lines conveniently, quickly and accurately.

Product Names:transmission line abnormal frequency parameter test system, line parameter tester
