| Description
| - This paper is focused on diagnostics methods for mechanical faults of power transformer windings. The principal of these methods is based on comparison of power transformer transfer functions. Basically, there are three ways how to obtain frequency response of transformer - the Low Voltage Impulse Method (LVIM), the Sweep Frequency Response Method (SFRA) and the method, which uses the CHIRP signal for acquisition of the transfer response. Nowadays the measurement part is solved and main attention is paid to the evaluation process. The original evaluation system was suggested. The system on the basis of acquired frequency characteristics, methods selection and suitable adjusted weights for each frequency band, gives information about eventually change of transformer winding condition. There was created knowledge-based system for decision-making process with three defined criterions as input values. Whole evaluation process was realized in the software MatLab.

- Příspěvek je zaměřen na oblast diagnostických metod pro detekci mechanických poruch vinutí výkonových transformátorů. Princip těchto metod je založen na porovnání přenosových funkcí transformátoru. Pro měření přenosových funkcí lze využít metodu nízkonapěťových impulzů , metodu frekvenčních charakteristik případně metodu využívající signálu CHIRP. V současné době je oblast praktického měření vyřešena a hlavní pozornost je věnována vyhodnocení. V příspěvku je popsán návrh vyhodnocovacího systému, který je založen na třech kritériích. Tato kritéria jsou vstupem do pravidlového expertního systému, který provede vyhodnocení. (cs)
