Technická diagnostika netočivých elektrických strojů

Abstract

The thesis deals with technical diagnostics of transformers focusing on preventive maintenance of these devices, solving faults in transformers as well as considering long-term trends of evaluated parametres of these devices. The first part is concerned with the description of diagnostics methods that are applied to these non-rotating electrical devices.The second part aims at looking into particular technical diagnostics methodsapplied for determining technical condition of the selected oil transformer. The third part follows up the evaluation of quantities measured applying the individual methods and finally it presents the conclusion for operating the diagnosedoil transformer. The final part sums up benefits of technical diagnostics for operating, maintenance and life efficiency of oil transformers. Also, it considers the importance of individual methods applied for diagnostics of the selected transformer.
