The influence of motor reacceleration on voltage sags [PDF]
IEEE Transactions on Industry Applications, 1995 The assumption that a voltage sag is rectangular is not correct in a power system with large induction motor loads. The motors decelerate during the short circuit. After fault-clearing, they will accelerate again, drawing a high reactive current from the supply, causing a prolonged postfault voltage sag. This is aggravated by the removal of branches by

Evaluation Method and Probabilistic Index of Voltage Sag Severity Considering Point-on-wave
Journal of Modern Power Systems and Clean Energy, 2021 The impact of voltage sag on sensitive devices is related to the time when the sag occurs. However, the point-on-wave of a sag is uncertain. Therefore, this paper presents a novel approach to evaluate the voltage sag severity considering a random point ...

A Voltage Sag Pattern Classification Technique [PDF]
, 2005 This paper presents an investigation on pattern classification techniques applied to voltage sag monitoring data. Similar pattern groups or sets of classes, resulting from a voltage sag classification, represent disturbance categories that may be used as indexes for a cause/effect disturbance analysis.
