20.500.12556/DKUM-75632 Zaščita proti prenapetosti v nizkonapetostnem omrežju diplomsko delo Overvoltage protection in low-voltage networks V diplomski nalogi je predstavljeno delovanje prenapetostne zaščite v nizkonapetostnem omrežju. Opisani so vzroki in posledice, ki nastopijo ob prenapetostih, pa tudi posamezni prenapetostni odvodniki. Prav tako je predstavljen standard SIST EN 62305-4, ki opisuje zaščito za električne in elektronske naprave v zgradbah pred udari strel. Na koncu sta še dva primera izračunov induciranih napetosti v zankah električnih inštalacij in tokov, ki stečejo ob udaru strele. The dissertation introduces the operation of overvoltage protection in a low voltage network. The causes and consequences of overvoltages as well as individual overvoltage arresters are described. The standard SIST EN 62305-4 is also presented, which describes the protection for electrical and electronic devices in buildings against impact. Finally, there are two other examples of the calculation of induced voltages in loops of electrical installations, as well as of currents that flow when lightning strikes. napetost odvodnik prenapetost prenapetostna zaščita strela tok voltage arrester overvoltage surge protection arrow current true true false [M.
