\n\t\t\t\t\t\t\t\t\tThe GEMS team’s research is situated in the context of the major economic and social challenges associated with the energy transition. They aim to strengthen the electrical vector, both in the deployment of renewable energies and their high-voltage transport, and in the revolution of industrial miniaturization aimed at contributing to the development of tomorrow’s electrical power systems. They also aim to provide new tools for the understanding of fundamental physical phenomena in order to eliminate scientific barriers.\r\n\r\nThe work of the team is related to materials, components and systems for electrical energy, with two application areas which are electrical mobility, land, water and air, and large electrical networks. They are declined in two sub-themes<\/strong>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Structures and insulating materials subject to high stress:<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tThe destruction or decrease in performance of insulating layers is very often the cause of failures observed in components and systems. Insulating materials thus play an essential role in the reliability of electrical and electronic applications where the financial stakes or in terms of human safety are decisive, but also in large-scale distributed applications.\r\n\r\nThe GEMS team is interested in understanding, in the short and long term, the dielectric phenomena that develop in materials under the effect of thermal, electrical and environmental constraints. Their study and analysis allow to increase the reliability through a choice of material and an adapted design of the component, the modeling of its aging and\/or the development of new materials. The targeted applications are energy transport, embedded systems (aeronautics, automobile, space), high performance equipment, sensors and any application integrating insulating layers subjected to strong electrical and thermal constraints.\r\n\r\nThe study and the understanding of the phenomena aiming at the development of materials with high dielectric performances constitute the main objectives.\r\n\r\nThe solutions developed by the GEMS team by S. Agnel, J. Castellon, J-C. Laurentie and P. Notingher are based on approaches that closely link experimental and modeling approaches, using original methods that can be directly adapted to components and implemented on site. These are in particular the so-called “thermal stimulus” techniques, which the team is developing and for which it enjoys a strong international recognition. The current dynamics is linked to the future high voltage energy networks, necessary to transport high power over long distances (“super-grids”) and whose main limiting factors are the materials for cables and equipment. Research also concerns bio-based and nanostructured materials for electrical engineering applications, as well as insulators used in electronic components.\r\n\r\nThanks to its strong links with specialists in materials engineering, the team covers a wide range of aspects related to the development and aging of insulators. It has important means of dielectric studies, some of them without equivalent at the French and world level.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
