Especially, the power failure of the extra-high voltage line has great influence on the operation safety, reliability and economy of a power grid. Live working is an important technical means for ensuring the operation reliability of a power grid.

Particularly, the conductive defect is not easy to be found after the conductive defect appears in the composite insulator. If live-wire workers work near a composite insulator with a conductive defect, after the defect develops to a certain degree and a gap of a short-circuit part of the worker, internal breakdown can occur under the operating voltage or overvoltage to cause a drop or casualty accident, the national standard, the electric power industry standard and the enterprise standard of China are clearly specified, before live-wire work is carried out on a porcelain insulator of a power transmission line, zero and low values of the porcelain insulator are measured, after the number of good insulator pieces meets the safety requirement of the live-wire work, the work can be carried out, and a mature porcelain insulator detection device is provided in China.
