Dielectric absorption of insulating system generators in operation

Original language description

One of the important diagnostic methods used in insulating systems of large rotating electrical machines is method for measuring charging currents, for which is the dominant part the absorption currents. Charging currents are measured by diagnostic groupČEZ nearly half a century. These values were used for measurements of three hydrogenerators and two turbogenerators, for this study. All used machines have insulation system in temperature class 155 °C. The results were compared with measurement resultsfor systems with temperature class 130 °C. This article contains graphic processing of dielectric absorption for the insulation system temperature class 155 °C. This graphic processing did not show a clear change neither during the thirty years of measuring insulating systems of these machines.
