    Conference report
    Open Access
    Fundamento y Métodos: En esta investigación se presenta el caso del análisis de un accidente del sector minero a través de 2 métodos distintos: 1) árbol de causas, 2) Feyer & Williamson. En el método del árbol de causas ...

  • Short-term energy storage for power quality improvement in weak MV grids with distributed renewable generation 

    Díaz González, Francisco; del Rosario Calaf, Gerard; Girbau Llistuella, Francesc; Gomis Bellmunt, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Conference lecture
    Open Access
    The intermittent and stochastic nature of renewable energy sources impose several challenges for the operation of electrical networks, and affect power quality levels as well. This paper addresses one of the issues associated ...

  • Natural observatories for lightning research in Colombia 

    Aranguren Fino, Harby Daniel; López Trujillo, Jesús Alberto; Montañá Puig, Juan; Torres Sanchez, Horacio (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    This paper presents a selected, not exhaustive, description of lightning research in Colombia over time, based on natural observatories for experimentation and measurement; and introduces the DABEIBA Lightning Research ...

    En este trabajo se presenta el nuevo laboratorio E3PACS de investigación en micro-redes, sus características y equipamientos. Dicho laboratorio se encuentra situado en el edificio A de la Escola d’Enginyeria de Barcelona ...

  • Automated analysis and statistics of lightning leader speed, local flash rates and electric charge structure in thunderstorms 

    Van der Velde, Oscar Arnoud; Montanya, Joan; López Trujillo, Jesús Alberto (2018)
    Conference lecture
    Open Access
    We introduce new methods for the analysis of complex three-dimensional lightning data produced by Lightning Mapping Arrays and illustrate them by cases of a mid-latitude severe weather producing thunderstorm and a tropical ...

  • Evolution of gigantic jets at high temporal and spatial resolution 

    Van der Velde, Oscar Arnoud; Montanya, Joan; López Trujillo, Jesús Alberto (2018)
    Conference lecture
    Open Access
    Gigantic Jets (GJ) are lightning discharges between the cloud and the lower ionosphere, which manifest as leaders at low altitude and transition to streamers as they rise in altitude. The evolution has never been imaged ...
