Abstract :
In this work the radiation of the electromagnetic field due to partial discharges throughout the insulation spacer of Gas Insulated Switchgears is investigated. Radiation can be described in terms of resonant modes of the slot between the metallic bolts and of the parallel plate between the metallic flanges. The geometrical characteristics of the spacer, that contribute to the emission of power toward the environment, are investigated.
