    • 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)
      Conference report
      Open Access
      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 ...
    • 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
      Open Access
      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 ...
    • 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
      Open Access
      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
      Open Access
      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 ...
