Abstract
Main objective of this dissertation is to execute and define monitoring system of block and tap-hanging oil power transformers currently placed in both blocks of Nuclear Power Station Temelín.
Construction, installation, auxiliaries, life-cycle and malfunctions of oil power transformers are described in first theoretical part.
Second part is focused on project of the most suitable monitoring system specified for oil power transformers, on structure and equipment of this system, single parts of machinery used for registry and analysis of quantities, evaluation of the most effective way of quantity monitoring that is necessary for trouble-free performance of transformers.
At last follows demonstration of utilization of this monitoring system while all oil power transformers of the block are switched on along with processing and analysis of obtained data and example of data outcome used for monthly control of transformer's performance.
