New method for voltage sags characteristics detection in electrical networks

Voltage sag is one of the most important problems of the power quality which affects the new sensitive equipments. For analysing the effects of voltage sag on these equipments, we need to establish a method for the voltage sags characterization. This paper presents a new method for detecting the type of voltage sags, from real-time measured data, method that will be implemented in an algorithm, for monitoring the voltage sags in distribution electrical network.
