Original Abstract
This article deals with possibilities of localization of the partial discharges (PD) in oil power transformers. Localization can be performed on the basis of measured UHF waveforms analysis during activity of the partial discharges. The time-shifts of the waveforms related to transient process occurrence in the signals are the main input parameters for localization methods. In order to estimate the position of the signal source in the 3D space a minimum of four antennas has to be used, since the time of the PD is unknown. Designed application uses a numerical method for detection of the discharge spatial location. Diagnosis of the partial discharge is split into four Gross. At frst, time graphs of detected signal are displayed for its visual verifcation. Each group of displayed signals include time stamp of the actual trigger. This time stamp is used as information for visualization of the position of the signal group in time range of the power voltage period. Third part is focused on the spatial detection of measured discharges in volume of the transformer. At least, statistical results are shown.
