Electric Strength of Dielectric Materials in a Hostile Environment

Abstract

In connection with the fact that dielectric materials used to fabricate various parts of high-voltage electrical equipment systems, nuclear and thermonuclear reactors, and electronic devices often operate in ionizing radiation fluxes, problems of radiation resistance and charging of insulating materials and devices are urgent. The researchers involved in the development of accelerator technology and nuclear power engineering from the outset search for radiation-resistant insulation and structural materials, and develop ways to improve the radiation resistance of novel and conventional materials (by the radiation resistance of materials is meant their ability to maintain their basic properties during and after irradiation). Considerable attention has recently been paid to the study of physical processes in dielectrics, supporting the construction of empirical models and the development of engineering methods for predicting the behavior of dielectrics in ionizing radiation fluxes [168].
