Research of Safety Protection for Live Working on 1000kV AC Ultra High Voltage Transmission Line

Safety protection research for live working on 1000 kV AC transmission line was made. The screening clothes for live working was developed and tested. Both material of clothes and the characteristics were researched with standards. According to the actual situation of operation, the electric field intensity on different parts of body and the current passing through human were measured in equal-potential process. The research results show the clothes can meet the safety protection requirements for live work on 1000 kV transmission line. The working man should wear full set screening clothes with face screening mask and the potential rod should be used during equal-potential process.
