Abstract :
This paper presents an evaluation study for measurement protocols of characteristic parameters related to short duration voltage variations (SDVs). The evaluation of possible differences in the magnitude and the duration of SDVs produced by different protocols is of great importance, for the electrical system performance indices related to voltage sags and swells are in practice obtained by measuring instruments. The study made use of a digital simulator that generated voltage conditions resultant of faults in a distribution network. Several measurement protocols for SDVs were applied and an overall comparison was performed
