A model to explain the TSDC spectrum of XLPE insulation in mid voltage cables based on a virtual electrode
Belana Punseti, Juan; Diego Vives, José Antonio; Orrit Prat, Jordi; Mudarra López, Miguel (2007)
Comunicació de congrés
Accés obertThe analysis by TSDC of a large variety of cables subjected to long annealing times, has resulted in spectra that sometimes show an oscillation of the current peak observed at 99°C. This process has been observed in some ... -

Method to distinguish between space-charge and dipolar relaxation in the TSDC spectra of polyethylene electrical insulation
Orrit Prat, Jordi; Cañadas Lorenzo, Juan Carlos; Sellarès González, Jordi; Belana Punseti, Juan (2010)
Comunicació de congrés
Accés obertMedium-voltage cross-linked polyethylene (MV-XLPE) cables have an important role in the electrical power distribution system. For this reason, the study of XLPE insulation may lead to improve cable features and lifetime. ... -

Study of dispersive mobility in polyimide by surface voltage decay measurements
Aragoneses Aguado, Andrés; Mudarra López, Miguel; Belana Punseti, Juan; Diego Vives, José Antonio (ELSEVIER PUBLISHER, 2008-05)
Article
Accés obertIn order to study charge trapping and transport in polyimide, we have submitted samples of Kapton HN to corona charging and measured its surface potential decay with an electrostatic voltmeter. We propose a two terms ... -
Transiciones y relajaciones en polímeros por el método de las corrientes de descarga estimulada térmicamente
