How fault current is calculated

WebThe simplest way of calculating fault current in a system is highlighted in IEEE 551-2006 (Violet Book) as: Where I_f is the fault current and E is the voltage and Z is the impedance. Theoretically, this implies that a current traveling through a solid line with barely any resistance would have a current close to infinity.
