Inspection and testing of tools, equipment and training for live-line work on overhead lines

Live-line maintenance on overhead lines is widely applied worldwide at low, medium and high voltage levels in both the grid of transmission and distribution system operators because of its technical and economic benefits. Unfortunately, there is not any common frame to define the required acceptance and periodical tests of equipment and their periodicity, so the duration and structure of theoretical and practical training. One of the main aims of this Technical Brochure is to harmonize these essential topics by defining complex and detailed guidelines to guarantee up-to-date knowledge and increase general safety of live-line maintenance at all voltage levels.
