Abstrakt EN: The issue of discharge activity is constantly encountered when operating electric devices of higher performances as well as higher working voltages. This paper provides a study of conditions in the stressed place of an insulation system, i.e. in a conductor outlet from a rotary machine stator slot. The simulation of an electric field distribution presented in this article is aimed to match reality as closely as possible. The trouble spot is located by both an electric field simulation and a practical measurement.
