Abstract
An electrically insulating material for high voltage generators is provided. The electrically insulating material comprises a polymer based dielectric material filled with nanoparticles, wherein the voltage at which partial discharges start in the polymer based dielectric material is greater than the voltage at which partial discharges start in an unfilled polymer based dielectric material.
