What is the significance of fault analysis in power systems, and how is fault location determined?
Voltage sags due to short circuit and earth faults are the cause for the vast majority of equipment problems. Electronics equipment become more susceptible to voltage sag, hence the companies experience production stoppages. Voltage sag analysis is very complex issue. Based on voltage sag randon factors describe on it.

The single-line diagram of a simple three-bus power system is shown in Figure-2. Each generator is represented by an emf behind the sub-transient reactance. All impedances are expressed in per unit on a common MVA base. All resistances and shunt capacitances are neglected. The generators are operating on no load at their rated voltage with their emfs in phase. A three-phase fault occurs at bus 3 through a fault impedance of Zf = j0.19 per unit.
