    • Corona discharges from grounded rods under high ambient electric field and lightning activity 

      Sousa Arcanjo, Marcelo Augusto; Montanya Puig, Joan; Urbani, Michele; Fontanes Molina, Pol; Lorenzo, Victor; Pons Montserrat, Enric (2021)
      Text en actes de congrés
      Accés obert
      We assess results of corona pulses detected under high background electric field in the laboratory and in the field in two different experimental sites. The first location is on the roof of a regular building, and the ...

    • Experiments with a tethered drone to investigate induced charges on a vertically arranged conductor during fair weather 

      Sousa Arcanjo, Marcelo Augusto; Fontanes Molina, Pol; Urbani, Michele; Montanya Puig, Joan (2021)
      Text en actes de congrés
      Accés obert
      To better understand the phenomena associated with electrostatic charges and potential distribution over vertical conductors, this work describes preliminary results obtained with a tethered drone that is used to lay ...

    • High-energy radiation from natural lightning observed in coincidence with a VHF broadband interferometer 

      Urbani, Michele; Montañá Puig, Juan; Van der Velde, Oscar Arnoud; López Trujillo, Jesús Alberto; Sousa Arcanjo, Marcelo Augusto; Fontanes Molina, Pol; Romero Durán, David; Roncancio Guzmán, José Andrés (2021-04-16)
      Article
      Accés obert
      This work presents the first simultaneous X-ray measurements from natural lightning in coincidence with a very high frequency (VHF) broadband interferometer. During an observational campaign in north-central Colombia, five ...

    • Measuring low-current discharges from grounded rods under high background electric fields 

      Sousa Arcanjo, Marcelo Augusto; Montanya Puig, Joan; Urbani, Michele; Lorenzo, Victor (Elsevier, 2023-04-01)
      Article
      Accés obert
      This work presents the development of an inductive current sensor for measuring pulsating corona discharges observed under high background electric field. Laboratory and field experiments in different setups are used to ...

    • Multi-stroke positive cloud-to-ground lightning sharing the same channel observed with a VHF broadband interferometer 

      Urbani, Michele; Montañá Puig, Juan; Van der Velde, Oscar Arnoud; Sousa Arcanjo, Marcelo Augusto; López Trujillo, Jesús Alberto (2022-04-15)
      Article
      Accés obert
      In the same lightning flash, whose usual duration is less than a second, there can be multiple negative cloud-to-ground strokes with different terminations or following a preexisting channel to the ground. In contrast, it ...

    • New era of lightning detection from space: application to electric power systems 

      Montañá Puig, Juan; López Trujillo, Jesús Alberto; Van der Velde, Oscar Arnoud; Solà de las Fuentes, Glòria; Romero Durán, David; Morales Rodríguez, Carlos Augusto; Visacro, Silverio; Goodman, Steven J.; Williams, Earle Rolfe; Peterson, Michael J.; Pineda Rüegg, Nicolau; Sousa Arcanjo, Marcelo Augusto; Aranguren Fino, Harby Daniel (2021)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Information about lightning activity and its parameters is necessary to design and evaluate the lightning protection of an electrical power system. This information can be obtained from ground-based lightning detection ...

    • 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, ...

    • Optical signatures associated with streamers and leaders of laboratory discharges 

      Sousa Arcanjo, Marcelo Augusto; Montañá Puig, Juan; Urbani, Michele; Lorenzo, Victor (2021-10-28)
      Article
      Accés obert
      This work investigates the strongest optical emissions associated with long laboratory sparks (at the wavelengths of 337 nm and 777 nm) with the aim to understand similar emissions in lightning. The processes of the ...

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

      Montañá Puig, Juan; López Trujillo, Jesús Alberto; Van der Velde, Oscar Arnoud; Solà de las Fuentes, Glòria; Romero Durán, David; Morales Rodríguez, Carlos Augusto; Visacro, Silverio; Saba, Manuel; Goodman, Steven J.; Williams, Earle R.; Peterson, Michael J.; Pineda, Nicolau; Sousa Arcanjo, Marcelo Augusto; Aranguren Fino, Daniel (2022-12)
