Conclusion de cette étude (en anglais)

  • Timestamping of outages and return stroke are crucial parameters for lightning-caused outages correlation : Zero second delay guarantees the quality of the correlation.
  • The distance between strokes and assets locations is subject to errors related to Lightning Location System and Assets geo-referencing accuracy. This parameter value must be adapted in the correlation system according to both uncertainties.
  • For ENEDIS, it is recommended to use a correlation distance not smaller than 2 km since head-end stations serve as reference points for the spatial correlation.
  • Another parameter to consider in the correlation process is the Ipeak current.
