A Practical Solution for Locating the Source of Voltage Dips in HV/MV Interconnected Grids

Monitoring the technical performance of a power system is significantly enhanced when distributed instrumentation produces coherent field data, i.e., synchronized by GPS timestamping. In this paper practical methodology presented to improve localization source voltage dip on grids. The proposed solution makes use data provided quality meters. Field reporting events occurred in an HV/MV interconnected South Africa are used validate results obtained improved method and compare with two alternative methods.
