In order to clearly identify responsibilities for voltage quality disturbances on the point of connection (POC), voltage and current requirements have to be available at the POC. So the relation between inrush currents, flicker severity levels and grid impedances in the low voltage grid should be explained. Furthermore maximum harmonic currents at the POC in low voltage grids are determined by using these grid impedances.
J Cobben explains how he and his team developed a very simple ABCDEF classification to help everybody having a common tool to assess power quality requirements.
