The rapid construction of power grid in China has promoted the development of live working technology. After 60 years of research and practice, China＇s live working technology has made great progress and been widely applied, leading the world in ultra high voltage （UHV） live working. In order to meet the requirements of operation safety for UHV and extra high voltage （EHV） transmission lines and to enhance the reliability of distribution network, further research on live working is needed urgently. According to the development history and current situation of live working in the world, we summarized the key technical problems and the main research achievements in live working on AC＆DC transmission lines in China, in the aspects of key parameters, personnel safety protection methods, tools and apparatus developed, and established standards. We also introduced the research progress, standard setting and simulative training of live working on distribution lines and substations. Considering the development and the application requirement of new technology and equipment in power grid, we discussed the developing trend of live working technology, as well as some key projects including the UHV live working tools and instruments, the application of helicopter and aerial lift device with insulating arm for live working on transmission lines, and bypass work in urban distribution networks.
