The thesis describes the procedures of revision of a substation. This focuses on a precise examination and analasis of the key components of the station. It is also described what all falls under maintanance of electroenergetic systems, which include regular check ups, preventive measures, reparations and equipment updates, which are all crucial for extending the lifetime of the system and preventing unexpected malfunctions.
For an example I chose Substation Škofja Loka. The revision, which was carried out after the recent reconstruction of the substation, consisted of a complete examination of switchyards, transformers and protection systems, with the goal to ensure optimal operation and reliability of the electroenergetic system.
In the thesis I especially concentrated on the comparison of two switchgear cells, which were analysed based on their technical characteristics, reliability, endurance and suitability for specific operation conditions. The comparison showed the key differences between the two cells, which has an important influence on the choice of the substation equipment.
