  报告人: Gilbert Teyssèdre




Gilbert Teyssèdre, born in 1966, received his Engineer degree in materials physics and graduated in solid state physics in 1989 at the INSA, Toulouse, France. Then he joined the Solid State Physics Lab in Toulouse and obtained the Ph.D. degree from Paul Sabatier University in 1993 for work on ferroelectric polymers. His research activities concern the development of luminescence techniques in insulating polymers with focus on chemical and physical structure, degradation phenomena, space charge and transport properties. He is currently Senior Researcher at CNRS. He has been head of the Solid Dielectrics and Reliability group at Laplace from 2004 to 2015. He has held numerous governmental and industrial research grants in the field of electrical insulation and has co-authored over 160 contributions to scientific journals and book chapters and 230 conference proceedings. He is member of the scientific committee of several conference series as CEIDP since 2016, ICD, ICEMPE, and JiCable. He is Associate Editor of IEEE Trans. Dielectr. Electr. Insul (2021-).


The development of HVDC cable technologies concerns cable itself and also accessories used for jointing cable sections and terminations of cables. Accessories constitute a critical part, especially when going to high voltage. We will show how far the field redistributes when associating different materials, dynamically with accounting for the temperature gradients set-up in the accessory through 3D field estimations. Field grading principles will be described along with challenges for improving simulations of the field distribution.
