Višestruki trajni kvar dalekovoda uzrokovan klimatsko-atmosferskim utjecajima stvarnost su koja pogađa mnoge elektroenergetske sustave. Izravne štete zbog tih kvarova vrlo su velike, no marginalne su u odnosu na društvenu štetu uzrokovanu redukcijom potrošnje električne energije. Kako je neekonomično graditi dalekovode otporne na atmosferske utjecaje, treba nastojati preventivnim akcijama što efikasnije sanirati nastale štete, odnosno skratiti rokove popravaka.
Radna skupina CIGRÉ (WG B2 13) priredila je Upute za djelovanje u kriznim situacijama temeljenim na iskustvima velikih poremećaja.
I naša iskustva s višestrukim trajnim kvarom dalekovoda kao i značaj naše prijenosne mreže dovode do zaključka da bi bilo mudro da HEP OPS pristupi odgovarajućoj organizaciji preventive u dogovoru s HERA-om. U manjoj mjeri taj se problem odnosi i na sabirnice 400 kV.Multiple failures of transmission lines caused by climatic/atmospheric impact plague many electric power systems. Direct damage from such failures is quite huge, yet it is marginal compared with the social damage caused by the reduction in the supply of electricity. As it is not economical to construct weatherproof transmission lines, preventive actions should be employed the most effective restoration, or to reduce restoration time.
A working group of CIGRÉ (WG B2 13) has prepared emergency guidelines based on the experience of large-scale disruptions. Our experience with multiple transmission line failure, as well as the importance of our power grid, lead to the conclusion that it would be wise for HEP OPS to begin with an appropriate organisation of preventive actions in agreement with HERA. To a lesser extent, this also applies to 400 kV buses
