Grounding requirements to assure people and equipment safetyagainst lightning

摘要

In places of high lightning activity, as it is the case ofFlorida, in the US, and Amazonia, in Brazil, lightning is an importanthazard, for people and equipment, specially in installations with highantennas and radar towers, and for electronic equipment. To obtainsafety, one essential aspect is to adopt adequate grounding systems,with the eventual need of additional measures, such as shielding andovervoltage limiting equipment, and masts and shielding cables, to limitcurrent amplitude of lightning strikes incident in protected zones. Wepresent the most important methodologies and procedures, that allow usto consider such aspects in a coordinated and practical way. Theexamples are related to concrete projects
