Sažetak
The restructuring of the electricity market that occurred in the previous years has led to a change in the approach to the maintenance of equipment, stations and grid elements. With the liberalization of the market, profit becomes the most important aspect in power system exploitation, hence, in order to avoid costs, there is a reduction in preventive maintenance procedures for both transformers and other equipment. This inherently reduces the safety and reliability of the system. In order to maintain the level of safety and reliability of operation at a sufficient level, they are replaced by systems of occasional or continuous monitoring and periodic thermal imaging. The most effected grid elements are energy transformers which are coherently the most important and most expensive elements of the grid. Determining the availability of power transformers is important for the safe operation of the power system. Transformer monitoring and diagnostic systems are particularly interesting for more efficient resource management, increasing system reliability and safety while preventing unwanted consequences or grid faults. Monitoring systems have poor diagnostic properties and are, therefore, combined or supplemented with other methods or procedures. Additionally, new diagnostic methods and techniques are being investigated that could continuously monitor and diagnose the condition of transformers. Thereby, different thermal imaging procedures present an unavoidable factor in proper transformer diagnosis.
