Enhancement of fault analysis method using ARC resistance formula

Generally there are two different methods in calculation short-circuit currents in power system networks in terms of considering arc resistance in calculations, first method is based on considering the value of the arc resistance as a constant value (usually 0.5O) or neglecting this value. By introd...
