Evaluation of arc conductance for high current fault arcs

Generally, standard electric arc models are of very much importance in order to study the arc behaviour and its performance in the circuit. Considering the dynamic nature of arc, it is necessary to precisely simulate the electric arc models to perform correct arc flash calculations in order to use those arc for the applications like short circuit tests and power system fault studies. This paper discusses the several arc models used to calculate arc conductance for various fault arc currents, which will be used for calculating the short circuit test parameters for real-time short circuit testing of surge arrester in High Power Laboratory, CPRI Bangalore.
