The field of interest of DEIS comprises the study and application of dielectrics from the molecular level, through nano-structured materials, to insulation systems in industrial, commercial, and power system equipment. It also covers new applications such as those at ultra-high voltages (UHV) and in other small-scale systems like biology. The scope of the technical activities of DEIS covers the advancement of basic science, as well as the education of practicing engineers in using emerging dielectric materials, and the development of standards for the prudent application of existing and new insulation systems.
The technical activities of DEIS are currently carried out within framework of the following technical committees involving experts from academia and industry.
