Is your surge protection strategy adequate for dealing with extreme environments?

摘要

Relevant data and basic calculations can determine the level of lightning protection needed for a particular facility. HIGH-RELIABILITY SYSTEMS REQUIRE system up-times that approach reliability requirements of 99.9999 percent. Putting this requirement in perspective, this translates to a system that is operational for 8,759 hours, 59 minutes, and 30 seconds every year, leaving only 30 seconds of down-time for unplanned maintenance, power failures, equipment failures, etc. To meet the demands of high-reliability systems, components used in those systems must be capable of operating in numerous adverse environmental conditions. These include common environmental stresses such as temperature and humidity, as well as those stresses associated with nearby and distant lightning activity.
