Hodnotenie diagnostiky transformátorov

Abstract

In this bachelor thesis, I focused on the diagnostics of power transformers, which are key compo-nents of the electrical power system. The main objective of this work was to evaluate the technical condition of three specific transformers based on selected diagnostic measurements. In the theoretical part, I described the basic operating principles of transformers, their construction, and the ageing processes of the insulation system. In the practical part, I compared the measured values of individual transformers, which made it possible to assess the influence of ageing and ope-rating conditions on their technical state. Based on the obtained results, I evaluated their suitability for further operation and identified pos-sible degradation of the insulation system. At the same time, I aimed to highlight the importance of diagnostics in preventing failures, increasing operational reliability, optimizing maintenance, and reducing operating costs.
