Live working. Minimum approach distances for a.c systems in the voltage range 72,5 kV to 800 kV. A method of calculation1 Scope This International Standard describes a method for calculating the minimum approach distances for live working, at maximum voltages between 72,5 kV and 800 kV. This standard addresses system overvoltages and the working air distances or tool insulation between parts and or workers at different electric potentials. The required withstand voltage and minimum approach distances calculated by the method described in this standard are evaluated
