In particular, significant changes have been made to the sections devoted to indicators and voltage alarms, and the standards for electrical testing of the working parts of indicators have been adjusted.
The section “Portable grounding” has been significantly revised. The requirements for portable grounding wires and the methodology for selecting their sections in operation have been clarified and brought closer to the requirements of European countries and brought into compliance with current Russian standards. A number of requirements for portable grounding rods have been clarified in connection with the trend of using grounding installation methods in electrical distribution networks without lifting personnel onto supports air lines power transmission
The list of protective equipment includes kits for protection against electric arcs, the range of protective equipment for the face, eyes, and respiratory organs has been expanded, stationary voltage alarms, ladders and insulating fiberglass stepladders have been introduced.
