Surge Arrester Installation in The Industrial Network
 Korejčík, Michal ; Šlezingr, Jan (referee) ; Orságová, Jaroslava (advisor)
The work deals with issues of transient overvoltages. The first part of the work is focused on the overvoltages generating during switching actions. Overvoltage, which is arising during interrupting small inductive current, is practically tested by program ATP. Next part of this work is engaged in an area of atmospheric overvoltages. There are described typical characteristics and parameters of atmospheric overvoltages. The following chapter is devoted to high-voltage surge arresters - the elements, which avert danger of serious equipment damage. Spark-gap arresters as well as MO-arresters are described in this work. Their general characteristics and typical parameters are being introduced. Finally, the last part of the work explains the concept of protective distance and the equation, after whose is protective distance determined. The concept is verified by the help of program ATP, in which it is possible to simulate the phenomena arising from the transient overvoltages.
