Øystein Leif Gurandsrud Hestad
About
My research and teaching focus on high voltage technology, insulating materials, breakdown mechanisms in polymeric insulations, ageing of dielectric materials, charge transport in dielectric materials, and numerical simulations (mainly using FEM software). I am passionate about advancing our understanding of electrical insulation systems and their performance under extreme conditions, particularly for high-voltage direct current (HVDC) applications.
My research combines experimental work with computational modeling to develop new insights into how materials break down under stress and the mechanisms behind electrical failures. I also have a strong interest in developing novel testing techniques and innovative solutions to real-world engineering challenges.
In addition to my research, I teach courses on insulating materials, high voltage equipment, and electrical power systems, and enjoy mentoring students, particularly in the areas of experimental research and simulation techniques related to high voltage technology.
