      We propose an experiment intended for undergraduate laboratories, with the aim to introduce different novelties as a subject for a practical session or students project. We deal with the different components of the resistance ...
    • Corona discharge characteristics under variable frequency and pressure environments 

      Bas Calopa, Pau; Riba Ruiz, Jordi-Roger; Moreno Eguilaz, Juan Manuel (Multidisciplinary Digital Publishing Institute (MDPI), 2021-10-08)
      Article
      Open Access
      More electric aircrafts (MEAs) are paving the path to all electric aircrafts (AEAs), which make a much more intensive use of electrical power than conventional aircrafts. Due to the strict weight requirements, both MEA and ...
    • Disseny i càlcul d'un motor síncron d'imants permanents per a un vehicle elèctric 

      Bas Calopa, Pau (Universitat Politècnica de Catalunya, 2020-07-24)
      Master thesis
      Open Access
      El motor elèctric és un dels sistemes més eficients per a convertir energia en moviment i tanmateix és de les màquines més senzilles. Malgrat aquesta aparent senzillesa, al darrere s’hi amaga tot un món de fenòmens ...
    • Measurement of corona discharges under variable geometry, frequency and pressure environment 

      Bas Calopa, Pau; Riba Ruiz, Jordi-Roger; Moreno Eguilaz, Juan Manuel (Multidisciplinary Digital Publishing Institute (MDPI), 2022-02-26)
      Article
      Open Access
      Aeronautical industry is evolving towards more electric aircrafts (MEA), which will require much more electrical power compared to conventional models. To satisfy this increasing power demand and stringent weight requirements, ...

      Bas Calopa, Pau (Universitat Politècnica de Catalunya, 2017-06)
      Bachelor thesis
      Open Access
      La tecnologia actual permet disposar de sistemes capaços de controlar les condicions atmosfèriques per a la incubació artificial d’ous d’ocells i per a poder mantenir les cries en condicions òptimes durant les primeres ...
    • Use of DSLR and sonic cameras to detect and locate high-voltage corona discharges 

      Riba Ruiz, Jordi-Roger; Bas Calopa, Pau (Multidisciplinary Digital Publishing Institute (MDPI), 2022-09-24)
      Article
      Open Access
      Corona discharges are a concern in high-voltage applications. It is of utmost importance to detect and locate the discharges at an early stage using simple methods for this purpose. This paper evaluates and compares the ...
    • Using CMOS image sensors to determine the intensity of electrical discharges for aircraft applications 

      Riba Ruiz, Jordi-Roger; Bas Calopa, Pau; Aziz Qolla, Yassin; Pourraz, Marc; Oksahin, Burak (Multidisciplinary Digital Publishing Institute, 2022-08-27)
      Article
      Open Access
      The development of more electric aircrafts (MEA) and all electric aircrafts (AEA) inevitably implies an increase in electric power and a consequent increase in distribution voltage levels. Increased operating voltages ...
