Abstract

Naloga opisuje precej neraziskano področje vpliva električne napetosti in toka na živali, natančneje živali gospodarskega pomena, kot so govedo, konji in drobnica. Celotno področje živinoreje je izrednega ekonomskega pomena in od rejca terja nenehno proučevanje in delo na terenu, da lahko uspešno gospodari. V nalogi je najprej predstavljen splošni pregled vpliva električnih veličin, predvsem na pašno živino. Sem spadajo vplivi zemeljskega toka pašnega električnega aparata, vplivi atmosferskih razelektritev (strel), vpliv blodečih tokov, ko je pašnik na kraških tleh v bližini železnice z električno vleko, in vpliv zemeljskega toka ob okvari visokonapetostnega daljnovoda, ki poteka čez pašnik. V nadaljevanju je opisanih več različnih možnosti zaščite živali, predvsem s stališča varovanja pred atmosferskimi razelektritvami. Na koncu so predstavljeni še primeri izračuna ocene tveganja zaradi udara strele. Potek besedila je zastavljen sistematično, tako da bralec najprej spozna pašo živine kot celoto, nato različne negativne električne dejavnike in šele na koncu primere zaščite, ki večinoma temeljijo na principu preventive.

Secondary title: RISK ASSESSMENT FOR LIVESTOCK PROTECTION AGAINST OVERVOLTAGES
Secondary abstract: The diploma work describes an unresearched area of the electrical affect to animals, precisely animals of economic importance such as cattle and horses. The entire area of livestock has a high economic importance and requires constant study and work in the field that can be successfully managed by the breeder. The first task is a general overview of the impact of electrical quantities to grazing livestock. These include the effects of the ground fault of electric fence energizer, the effects of atmospheric discharges (lightning), the impact of stray currents and influence of the ground fault of the high-voltage transmission line that runs across the pasture. Final part of the text also reports about the protecting animals against atmospheric discharges. In the end are presented examples for calculation of the risk assessment due to lightning. The text is structured systematically, from simple description of grazing management, then negative electrical affects and finally the examples of protection which are mostly based on the principle of prevention.
