Dip segmentation method

An alternative approach for the analysis of various types of dip events, termed Dip Segmentation Method, is presented in this paper. The description of a voltage dip in the proposed method includes both pre-dip and post-dip parts/segments of a dip-related event, while the during-dip part is divided into a number of “during-event segments” and “transition segments”. In that way, the proposed method allows for an improved assessment of standard and commonly used dip characteristics, incorporating, at the same time, several usually neglected characteristics, aspects and features of dip events into the analysis. After identifying the corresponding dip segments, direct correlation between the individual segments and particular effects on equipment operation could be established, allowing a more detailed description of the dip events and more accurate assessment of their influence on equipment performance.
