Grounding and lightning arrester protection on boats

U ovom radu istaknuta je važnost gromobranske instalacije na brodu. Gromobranska instalacija se izvodi tako da mogućnost udara u zaštićeni objekt od udara groma bude svedena na minimum. Zaštita od groma izvodi se tako da štititi posadu, putnike opremu te i samo plovilo od posljedica atmosferskog električnog pražnjenja (smrt, opekotina, požar, oštećenje). Uz pojavu snažnog zvučnog udara (groma) povezuje se i pojam munje tj. naglo pražnjenje atmosferskog električnog naboja koji je koncentriran u olujnim oblacima/između dvaju oblaka/između oblaka i tla. Gromobranska instalacija na plovilu sadrži iste elemente kao i ona na kopnu a to su: hvataljke, odvod, uzemljivač i dopunski pribor (po potrebi). Izgradnjom gromobranskih instalacija ne mogu se eliminirati sve štetne posljedice groma, ali se mogu svesti na najmanju moguću mjeru. Cilj rada je ukazati na mjere koje treba poduzeti na plovilu koji treba zaštiti da bi se smanjio rizik.In this work it will be emphasizes the importance of light bulb installation on board. The light bulb installation is performed so that the possibility of impact in a protected object from the storm stroke is minimized. Lightening protection is performed to protect the crew, passengers equipment and vessel from the effects of atmospheric electrical discharge (death, burns, fire, damage). Along with the appearance of a powerful impact (thunder), the concept of lightning is associated with the sudden discharge of atmospheric electric charge which is concentrated in the storm clouds, between two clouds and between the clouds and the ground. The light bulb installation on the boat contains the same elements as the ones on the mainland, which are: grips, drainage, earthing and accessories (if needed). The construction of lightning protection installations can not eliminate all the damaging consequences of lightning, but can be reduced to a minimum. The aim of the work is to point out the measures to be taken on a vessel to be protected to reduce the risk
