Abstract :
The usefulness of time-resolved measurements is shown for the study of degradation processes of insulating materials associated with partial discharges. Using an optimised test set-up the different stages in the degradation process can be recognised. The possibilities for using the time-resolved method in practice are discussed. A promising combination of classic and time-resolved measurements is presented and clarified by the first results obtained with the discharge analysing system TEAS
