I work on cell sites, grounding system design and repair is a primary design element, even then, the presumption in the industry is that if a site takes a direct hit - or for that matter a nearby strike - the equipment is a total loss.
The surge suppression gear we put in (lead ins at power feeds, RF feed, etc) is mostly to prevent a fire and to ensure the extra energy goes largely to ground.. but it won't prevent dead gear.
- logicallee 11y agoAre you saying essentially that "There is no such thing as a surge protector, they don't physically exist. Only surge reducers exist." Because that's what it sounds like to me. EDIT: All right, I'll rephrase. According to Google's infobox from nat'l geographic, lightning generates up to 1 billion volts. -> Are surge protectors at even the highest-end data centers simply not rated to a billion volts of surge protection?
- PhantomGremlin 11y agoThere's a "protector", but the protection isn't guaranteed to be 100% effective. That's an OK use of the language in this context and has many parallels in other fields. E.g. using a condom as protection against pregnancy and disease. Many people have learned the hard way that it's not 100%.
- Aloha 11y agoEffectively yes, when you're on lightning scale, yes. I use an isobar myself to power reduce noise, but I'm under no illusion that it will protect my shit from a direct strike.
