Measurement System of the Mean and Sub-Cycle LV Grid Access Impedance From 20 kHz To 10 MHz

This work presents a novel measurement method to characterize long-term and short-term variations of the LV grid impedance from 20 kHz to 10 MHz with configurable time, frequency and amplitude resolutions. The characterization of the grid access impedance in this frequency range is vital for the des...
