Occurrences of faults in power system contribute extensive voltage sags (dips) in a network. These occurrences have introduced problems to consumers mainly at 415V where sensitive control equipment is located. This paper investigates the propagation and travelling of voltage sag event under the influence of transformer connections and impedance line length. PSS/ADEPT (Power System Simulator Advanced...
Due to the increasing of power system fault and failure, voltage sag (dip) will occur instantaneously with respect to the fault and failure itself. The power system network consists of high voltage (HV), medium voltage (MV) and low voltage busbar (LV). Monitoring equipment in the power systems network are installed at strategic and appropriate 33/11 kV feeder. The propagation and the travelling of...
