Abstract in different language: As an essential tool for condition based maintenance of electrical equipment, PD measurements under real operating conditions are becoming ever more important. The main problems associated with these diagnostic on-site measurements are the measuring sensitivity and reproducibility of measured values with respect to calibration conditions. This paper discusses the problems of on-site PD measurement in medium voltage switchgear using a special PD-probe. It will be shown, that the maximum PD-sensitivity can be reached by using a capacitive sensor in conjunction with the PD-probe and by connecting of elements with resonance characteristics. For measurements made under operating conditions on real switchgear, a measurement sensitivity of < 20 pC could be reached.
