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.
1 Aging Factors

6 High Field and High Frequency Effects on Insulation
Advancing the technology of power modulators and repetitive pulsed systems and pertinent high voltage effects on insulation including theory, technology development, and applications. This encompasses phenomena such as high electric field stress, high magnetic flux, and high frequency issues relating to the performance of all insulating media. This will be achieved by accomplishing professional scientific and technical meetings, along with publications to disseminate the information to the power modulator and high voltage community. This committee will work closely with the International Power Modulator and High Voltage Conference (IPMHVC) Executive Committee, by supporting IPMHVC activities, generating review articles, and publishing special issues in the journals of DEIS.

7 Liquid Dielectrics
Coordinating technical activities and communicating knowledge concerned with use and evaluation of new liquid dielectrics. The evaluation of liquids includes assessment of long-term performance capabilities as well as of health and safety hazards associated with the use of liquids in electrical equipment. This will be achieved by arranging special sessions at DEIS meetings, organizing workshops on this topic, generating review articles, and publishing special issues in the journals of DEIS.
Chair: Dr. Bernard Noirhomme, Hydro-Quebec Research Institute, Varennes, QC, Canada
Following the emergence of knowledge in the field of nanodielectrics and assessing of the potential of these materials and material systems for enhanced performance of existing electrotechnical applications. The knowledge will be disseminated by arranging special sessions at DEIS meetings, organizing workshops on this topic, generating review articles, and publishing special issues in the journals of DEIS.
Chair: Dr. Michel Fréchette, Hydro Quebec Research Institute, Varennes, QC, Canada
9 Numerical Methods Applied to Dielectrics
Reviewing the state of knowledge on the numerical modeling of physical phenomena occurring in dielectrics including gas, liquids and solids, and to assess the progress accomplished with numerical simulation in the field of dielectrics over the past two decades. This will enable the anticipation and suggestion of future trends and the facilitation of collaborative actions. This will be achieved through arranging special sessions at DEIS meetings, organizing workshops on this topic and launching joint research initiatives.
Chair: Dr. Fulbert Baudoin, Université de Toulouse, Toulouse, France
10 Outdoor Insulation
