Abstract

This paper focuses on voltage sags. It introduces an automated approach to the analysis of voltage sags, their causes and impacts. The sag analysis is performed using software tools developed for this purpose. First, the software performs detection, classification and characterization of voltage sags. Next, if the voltage sag is caused by a fault, the software finds the fault location. Finally the software allows replaying of the sag waveforms for the purpose of evaluating of the impacts on equipment operation.
