Název v původním jazyce

Design of the evaluation process for transformer winding diagnostics

Popis výsledku v původním jazyce

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.
