Originální abstrakt
This article deals with possibilities of localization of partial discharges (PD) in oil power transformers. Localization can be performed by means of analysis of UHF waveforms which are measured during activity of the partial discharges. The time differences of arrival (TDOA) 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 3D space a minimum of four antennas has to be used, since the time of the PD occurrence is unknown. For localization purposes the system of nonlinear equations has to be solved. This can be performed by means of analytical or numerical methods. Both of the methods have their own advantages and disadvantages. The application of both approaches for signal source localization in measurement model will be presented in this paper. The methods will be compared in view of their suitability for a given configuration of antenna system
