标准摘要
Specifies a method for calculating the minimum approach distance for live working, at voltages between 1 kV and 800 kV, required to protect workers from system overvoltages. This standard addresses system overvoltages, and the working air distances between parts and/or workers at different potentials. The calculation of distances for d.c. voltages is presently under consideration.
