Abstract: The present disclosure relates to a method for determining phase connections of grid components in a power grid, the method comprising assessing a relative similarity of time series of measured voltage data of the grid components by clustering the time series of measured voltage data of the grid components; grouping the grid components into a plurality of clusters based on the assessing a relative similarity; and assessing a phase connection of the grid components in each cluster of the plurality of clusters. The present disclosure also relates to a respective device and computer program.
