      Article
      Accés obert
      We present in this paper lightning current measurements, LMA (Lightning Mapping Array) data and fast antenna electric fields associated with upward flashes observed at the Säntis Tower during summer of 2017. The LMA network ...

    • Meteorological aspects of self-initiated upward lightning at the Säntis Tower (Switzerland) 

      Pineda, Nicolau; Figueras i Ventura, Jordi; Romero Durán, David; Mostajabi, A.; Azadifar, M.; Sunjerga, A.; Rachidi-Haeri, Farhad; Rubinstein, M.; Montañá Puig, Juan; Van der Velde, Oscar Arnoud; Altube Vázquez, Patricia; Besic, Nikola; Grazioli, Jacopo; Germann, Urs; Williams, Earle R. (2019-12-26)
      Article
      Accés obert
      Interest in exploring the meteorological conditions favoring upward lightning from tall man-made structures has grown in recent years, largely due to the worldwide expansion of wind energy. To this end, instrumented towers ...

    • Meteorological aspects of winter upward lightning from an instrumented tower in the Pyrenees 

      Pineda, Nicolau; Montanya, Joan; Romero Durán, David; Bech, Joan; González Lopez, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Text en actes de congrés
      Accés obert
      A case study of winter upward lightning is analysed. In particular, the study focuses on the meteorological aspects that favoured the triggering of upward lightning by an instrumented tower in the eastern Pyrenees. Starting ...

    • Observations of corona point discharges from grounded rods under thunderstorms 

      Sousa Arcanjo, Marcelo Augusto; Montañá Puig, Juan; Urbani, Michele; Lorenzo, Victor; Pineda, Nicolau (2021-01-01)
      Article
      Accés obert
      We investigated features of corona point discharges when a grounded conductive rod is subject to a high background electric field. In the laboratory, high voltage is applied to an upper plate in a plane-to-point experiment, ...

    • Potential use of space-based lightning detection in electric power systems
