The subject of this paper is to analysis of the measurements results for voltage sags in modern distribution grids. Voltage signals were measured in a real European distribution grid at different locations at two voltage levels - 630 V and 1000 V. A sort of classification of these signals was performed, followed by a quantitative analysis of the depth and duration of the voltage sag, as well as the maximum value and duration of the Harmonic footprint. The results of the quantitative analysis were then statistically analyzed.
