【Abstract】 The development of an instrument for inspecting conductor defect on high voltage overhead transmission line is put forward in this paper. With the instrument the defects of the conductor on the high voltage overhead transmission line can be inspected whether the line is dead or in operation. According to the structural features of high voltage overhead transmission lines not only the defects in the steel core and in the aluminum part of the steel reinforced aluminum conductor can be detected by eddy current inspection and leakage magnetic flux inspection respectively, but also the defects in the grounding wire can be detected. The detection principle of the two inspection methods is analyzed, the concrete implementation and the structure of the instrument are described, the design of the software for signal processing is briefly presented. The results of on site and laboratory tests show that the detection result of this instrument is accurate.更多还原
