Abstract
One of the methods for diagnostic and assessment of the power transformers state is the measurement and analysis of broadband admittance/impedance characteristics of the windings. Such tests are realised by frequency response analysis (FRA) measurements, both in time and frequency domain. Usually Sweep Frequency Response Analysis (SFRA) method or Low Voltage Impulse (LVI) method with time-domain data transformation into frequency domain are used. However, other broadband signals may also be used for the identification of the broadband frequency characteristics. Theoretically, one of the signals that can be used to identify the transfer function parameters of tested circuits or systems is a white noise - random wideband signal. The report presents the results of the analysis of the signal properties of several pseudo-random white noise generators to evaluate their suitability in this type of study of transformers windings. The basic parameters of the voltage signals generated by them, important from the point of view of this diagnostic method, are compared. The influence of these parameters on the potential application of this type of stimulus for the study of transformer windings characteristics is analysed. The report presents and analyses the results of preliminary tests on the transformer windings, using low-voltage pseudo-random white noise signals.
