WebThe total fault current in (7.1.2), called the asymmetrical fault current,is plotted in Figure 7.1 along with its two components. The ac fault current (also called symmetrical or steady-state fault current), given by (7.1.3), is a sinusoid. The dc o¤set current, given by (7.1.4), decays exponentially with time constant T ¼ L=R. Webground fault current with respect to phase-neutral fault voltage, and two-phase fault current to ground [19].
