Lightning strikes are the significant cause of transient, faults, and outages in electric power transmission and distribution systems. The double-exponential function is proposed to simulate the decaying part of the measured lightning current. The transient characteristic difference (such as the gradient and waveform) between the common fault current and the lightning fault current is described in this paper. Thus, the criterion, which is to compare the peak value of transient current with the amplitude of transient current at the following 200...
