Abstract

Diplomska naloga obravnava prenapetostne odvodnike ter ugotavljanje prisotnosti uhajavega toka v le-teh v času, ko skozi prenapetostni odvodnik ne bi smel teči nikakršen tok. Prenapetostni odvodnik ščiti naprave v omrežju pred prenapetostjo ter tako poskrbi, da ob pojavu prenapetosti ščitena naprava ostane nepoškodovana. Ko prenapetosti ni, skozi prenapetostni odvodnik kljub temu teče neki mali tok, ki ne sme biti večji od 1 mA. Ta tok imenujemo uhajavi tok.

Secondary title:	MEASURING OF RESISTIVE COMPONENT OF SURGE ARRESTER LEAKAGE CURRENT
Secondary abstract:	In the degree dissertation it is dealt with the problematic of overvoltage arresters and identifying the presence of the leakage current in the exact time when nothing should be running through the overstrain arrester. The devices in the network are protected by the overvoltage arrester, which make sure that the protected device stays unharmed at the appearance of overvoltage. When overvoltage does not appear, there is still a small current (not more than 1 mA) running through the overvoltage arrester. This current is named the leakage current.
