PSpice Simulation of the Instantaneous Fault Current
The ac circuit shown in Figure 17.37a has R = 1.5 Ωand L = 15 mH. The load parameters are R_m = 5 Ωand L_m = 15 mH. The input voltage is 208 V (rms), 60 Hz. The circuit has reached a steady-state condition. The fault across the load occurs at ωt + θ= 2π; that is, θ= 0. Use PSpice to plot the instantaneous fault current.
