How to calculate the minimum value of the electric arc thermal effect of overalls?
Hello. Tell me how to calculate the minimum value of the HAZ of overalls (electrical installations of 0.4 kV and 6 kV)? And is it necessary to use a cap blank during switching in 6 kV networks? If so, in what documents is it written, and in general, in what documents are the requirements for clothes when switching in 6 kV networks?

Hello! The calculation can be carried out in accordance with IEEE 1584-2002 guidelines [9].
In accordance with the result of calculating the likely value of the energy of the incident heat flux generated by the electric arc, a set of the appropriate level of protection is selected for a particular electrical installation.
