The thesis is focused on the protection concept for medium voltage substation. The first theoretical part of thesis describes given medium voltage substation. Substation consists of two incoming feeders and six outgoing feeders. Due to the size of the substation was selected one outgoing feeder which is the subject of description and protection concept. Next part of the thesis is a description of the protective functions used to protect the elements in the selected feeder. This part contains a detailed description of the function and setting options for protection. The main part of the thesis describes calculation of specific protection functions and consequently with secondary testing of protective functions. Tests were performed on protective functions in the digital protections REF615 and REM620. The final part of the thesis deals with the evaluation of the secondary test results and verification saturation of the specified current transformers.
