    Abstract: Live working can effectively ensure safety and stable operation of ?800 kV ultra high voltage direct current (UHVDC) transmission line. Aiming at the live working of present study situation of ?800 kV UHVDC line, this paper analyzed the way that incoming line and outgoing line are equipotential and studied the operation safety distance and complex gap.   The safety protection  principle was determined and the insulator test method based on optical electric field intensity sensor was raised, which provide gist and reference for the live working of ?800 kV UHVDC transmission line.
               Key words: ?800 kV ultra high voltage direct current; live working; present situation analysis; insulator detection
