More Information
Summary:The invention relates to a parameter tester for a transmission line, mainly used for eliminating current interference between the same towers when testing the parameter of a transmission line. The parameter tester comprises a line parameter test control box, an impedance box and a data sampling device, wherein the impedance box is connected with a compensation device in parallel. After the parameter tester provided by the invention is adopted, the performance of the original instrument is not changed, the interference current of an adjacent alive circuit can be weakened; under the condition of strong interference, the parameter of the line can be measured conveniently and reliably; and meanwhile, the parameter tester has the characteristics of small volume, large capacity, light weight and the like, and realizes accurate test of parameters of constructed lines in the same tower.
