IEEE C62.82.2:2022

Abstract: The calculation method for selection of phase-to-ground and phase-to-phase insulation withstand voltages for equipment is presented. Methods for insulation coordination of different air-insulated systems like transmission lines and substations are outlined. The methods of analysis are illustrated by practical examples.
