Live working is the important technical method to ensure the safety and stability of ± 800 kV ultra high voltage direct current(UHVDC) transmission line operation, which has been researched and applied in recent years. Large amount of theory and practice experiences have been accumulated relatively. Aimed at the present situation analysis of live-working of ±800 kV UHVDC transmission line, some work was carried out. Firstly, the way of in and out of equipotential zone was analyzed. Next, the working safety distance and complex gap were studied. Then the safety protective principle of operating personnel was determined. Finally, a detection method for insulators based on optical electric field intensity senor was proposed. The work can provide useful reference for live working on ±800 kV UHVDC transmission line.
