The main aim of the present work has been the investigation of the characteristics of partial discharge current pulses as a diagnostic tool for electrical machines: in particular the possibilities offered by the Ultra Wide Band (UWB) partial discharge (PD) current acquisition technique have been thoroughly examined and implemented. This method allows to obtain information not only from the charge associated to the current pulse itself but also from the pulse waveform and therefore it can be used to discriminate among different types of PD sources and to provide hints for their localisation inside the insulation system. UWB techniques have been applied to the investigation of partial discharges within the windings of cast resin transformers even if observations on other types of MV equipment were carried out as well. A complete measuring system has been built around a fast digitizer thus obtaining an "open source" product which allows the analysis of several practical problems likely to influence the results, such as noise level and memory management techniques.
