Lightning and surge protection for rooftop photovoltaic systems and for free field PV power plants

Tema ovog završnog rada je sustav zaštite od munje i prenaponska zaštita fotonaponskih sustava na krovovima i fotonaponskih elektrana. Prvi dio rada je općeniti o pojedinim komponentama sustava za zaštitu od munja (o sustavu hvataljki, silaznim vodičima, sustavu uzemljivača) i o metodama štićenja (metoda kotrljajuće kugle, metoda mreže i metoda štićenog kuta). Drugi dio rada govori o primjeni sustava za zaštitu od munja i odvodnika prenapona na fotonaponske sustave.The subject of this paper is the lightning protection and surge protection of photovoltaic systems on roofs and photovoltaic power plants. In the first part of this paper I wrote general about components of the lightning protection system (air-termination system, down - conductors, earth-termination system) and about protective methods (the rolling sphere method, the mesh method and the protective angle method). In the second part, I wrote about application of the lightning protection and surge protective devices SPDs on photovoltaic systems
