Structure of Surge Arresters and Their Application in Power System
Strapko, Miroslav ; Novotný, Jan (referee) ; Orságová, Jaroslava (advisor)
This work deals with internal and external protection against surge phenomena occurring in the power system. Describes the atmospheric and the operating overvoltage. The main objective is to theoretically describe the issue of protection - surge arresters, which are used for different voltage levels from the view of parameters, use and construction. The last part shows the calculation of a sufficient gap between the devices of external protection against lightning - a safe isolating distance, the calculation of a protective distance of surge arresters and practical choice of overvoltage limiters for high-voltage transformer.
