Live working - Minimum approach distances - Part 2: Method of determination of the electrical component distance for AC systems from 1,0 kV to 72,5 kV
The withstand voltage and minimum approach distances determined by the method described in this document can be used only if the following working conditions prevail:
- workers are trained for, and skilled in, working live lines or close to live conductors or equipment;
- the operating conditions are adjusted so that the statistical overvoltage does not exceed the value selected for the determination of the required withstand voltage;
- transient overvoltages are the determining overvoltages;
- tool insulation has no continuous film of moisture present on the surface;
- no lightning is observed within 10 km of the work site;
- allowance is made for the effect of the conducting components of tools.
