Voltage sag propagation: Case study based on measurements
Paper i proceeding, 2006

This paper presents an analysis of the propagation of voltage sags caused by faults in a transmission grid. The investigation is performed considering a set of measured voltage sags obtained during a six month monitoring period. The analysis includes vertical and horizontal propagation and its quantification through a sag propagation index. The results show how the propagation of the disturbance is affected by the network topology, the transformers winding connection, and the load characteristics.
