Abstract	Načinjen je pregled najviše korištenih konstrukcija visokonaponskih podzemnih kabela, karakterističnih izvedbi kabelskih vodova, načina uzemljivanja zaslona kabela i pregled Cigré-ovih statistika podzemnih kabela. Opisan je postupak provedbe koordinacije izolacije na kabelskim vodovima, te su prema IEC normama za kabele s ekstrudiranom izolacijom i Cigré preporukama dani iznosi prenapona kojima trebaju udovoljiti kabeli kod ispitivanja i u pogonu. Na osnovu dostupne literature bazirane na IEC, IEEE i Cigré publikacijama su izrađene smjernice za izvedbu proračuna privremenih i atmosferskih prenapona u ATP-EMTP programu. U pregledu literature su opisani modeli pojedinih elemenata mreže za određene tipove proračuna. Proračuni sklopnih prenapona nisu provedeni, jer ukoliko izolacija kabela zadovoljava za atmosferske prenapone, zadovoljiti će i za sklopne prenapone. Za 110 kV kabelski vod u seriji s nadzemnim vodom su u ATP-EMTP programu provedeni proračuni privremenih i atmosferskih prenapona. Kabelska dionica je izvedena s prepletima zaslona kabela. Analiziran je utjecaj različitih parametara na iznose prenapona na kabelskoj dionici. Točnost proračuna nije eksperimentalno provjerena i temelji se na točnosti u literaturi eksperimentalno provjerenih modela pojedinih elemenata mreže. Na osnovu literature i dobivenih rezultata proračuna su dane preporuke za izvedbu zaštite od prenapona na visokonaponskim kabelima izmjenične struje.
Abstract (english)	An overview of most frequently used high-voltage underground cable constructions, cable configurations, cable sheath grounding and Cigré underground cable statistics has been done. Insulation coordination procedure for cable systems has been described and withstand voltage levels for cables during testing and operation have been determined according to IEC standards for extruded cables and Cigré recommendations. According to available literature based on IEC, IEEE and Cigré publications, guidelines for calculations of temporary and fast-front overvoltages in ATP-EMTP has been done. Network element models for conducted overvoltage simulations have been described according to the literature. Slow-front overvoltage calculations have not been conducted, as the cable insulation is assumed to satisfy the switching impulse insulation level if it satisfies the fast-front impulse insulation level. For 110 kV cable line connected in series with overhead line, calculations of temporary and fast-front overvoltages in ATP-EMTP have been conducted. Influence of different parameters on overvoltage levels on cable line has been analyzed. Simulations accuracy has not been experimentally verified and it is based on accuracy of in literature experimentally verified network element models. According to the literature and simulations results recommendations for overvoltage protection of overvoltage high-voltage AC cables have been done.
