Lightning Strike
This past weekend I pulled my back out putting in a water pond in my
backyard. When it was installed I have to admit that I did find it relaxing to sit on the back porch and listen to the water while doing my devotionals. I actually felt pretty good about how it was turning out. Until Monday night... Sherry and I were sitting downstairs watching the Tour de France when suddenly lightning flashed outside the window and the thunder crashed. It was a direct hit. It had hit my water pond! The pond was actually lifted out of the hole and the water was just about all gone. Fortunately we hadn't put fish in it yet or else we would be eating fish sandwiches! I have reinstalled the pond and checked into what contributed to my shocking experience. Could it be that by leaving the pump on during an electrical storm that a negative charge was created that the lightning was attracted to? |

Wow! That's one way to get rid of algae!
The pump should not have had anything to do with the strike. The way you described the damage the strike may have gone from the earth up or the pond is resting on or close to tree roots and the tree was hit. Electricity does crazy things.

Lightning seeks earth ground. If a pond makes the better
connection from cloud to earth, then so is your excitement. If miles of air did not stop lightning, then what difference is a silly little power switch or even the mythical surge protector. Lightning is not stopped, blocked, or absorbed except in myths. Franklin demonstrated effective protection in 1752. Lightning must be intercepted and diverted to earth to not find destructive paths through church steeple - or now through electrical and transistorized appliances. Protection for that pond would be a Franklin air terminal (lightning rod). Sharp or blunt rod? Irrelevant. That air terminal will only be as effective as its earth ground. Earth ground (not a surge protector) is surge protection. Others are still confused. They actually think a plug-in UPS claims protection from such surges even though the manufacturer makes no such claim. A UPS connects appliance directly to AC mains when not in battery backup mode. No protection there. Protectors only work when they connect the incoming surge to surge protection - earth ground. Again, nothing stops lightning. Lightning must be diverted to earth before it enters a pond or a building. Telephone and cable lines (are suppose to) have effective 'whole house' protectors or equivalent - to do what Franklin air terminals do. They earth the surge before it can enter the building. But the one incoming line that typically has no such protection is AC electric. Lightning to AC electric is, for example, the most common source of computer modem damage. Those who forget their elementary school science forget that a surge must first form a complete circuit. Only then is something in that circuit (ie modem) damaged. Nothing stops that surge. But a 'whole house' surge protector connected less than 10 feet to household central earth ground does provide effective protection from direct lightning strikes. This is but introductory. Further discussion among engineers can be reviewed in the newsgroup misc.rural in two threads: Storm and Lightning damage in the country 28 Jul 2002 Lightning Nightmares!! 10 Aug 2002 http://tinyurl.com/ghgv or http://tinyurl.com/ghgm Lightning may have struck the pond because a direct connection existed to breaker box earth ground. We do know that lightning struck that pond because pond was a best path to earth. Since household appliances were not in that path (no incoming and outgoing path through appliances as required by elementary school science on electricity), then appliances would not be damaged.

Well, I happened to have the paperwork from one of our APC UPS units right here, and it says (in part): "Power line transients that APC products have been designed to protect against, as recognized by industry standards, include spikes and surges on AC power lines."

Do those UPSes have surge protection? Which modes? Oh,
they forgot to mention there are different modes of surges? What numbers do they list for each type of protection? Post those specifications for a UPS that claims effective surge protection. I have been reading those specs for decades. I read the datasheets for components used to make surge protectors. Where is this claim on plug-in surge protectors - the URL? As noted previously, they claim protection from one type of surge. They don't claim protection from the surge that typically damages transistors. Lying by telling half truths will get a consumer to claim abilities that the manufacturer does not even claim. One plug-in protector, using same components in same circuit, was more honest: SL Waber EP63 Power Master This Surge suppressor is not a lightning arrestor and may not protect against lightning induced voltage surges. Why would APC, using same circuit, do what SL Waber could not? Quite frankly, APC does not claim that protection either. A surge protector is only as effective as its earth ground. No way around the most critical 'system' component - earth ground - that Franklin demonstrated in 1752 and that would be necessary to have protected that pond.

Which industry standard would that be? Computer Business
Equipment Manufacturer's Association? National Electrical Code? Underwriter's Laboratory? CSA? ISO? FCC Part 68? US Army's TM5-690? Which type of transients does APC claim to protect from? As stated previously, protection from a surge that typically does not exist. They do not claim protection from surges that typically damage electronics - or even ponds. So they make an ambiguous statement about protecting from "some" spikes and surges. They don't even say which ones, how long, or how big. In typical 'junk science' reasoning, they fail to provide numbers. Lets look at one standard that a surge protector claims to meet - UL1449 2nd Edition. UL does not test that anything works. UL only tests for threats to human safety. Testing for UL1449 does not care if the surge protector works or even survives. Survival is not relevant to human safety. UL1449 is about protecting humans from dangerous conditions such as shock and fire. UL1449 is not about testing to protect a transistor. Worded to make many think that UL1449 means a surge protector is effective. Actually, a surge protector can meet the criteria for UL1449 by making the protector less effective. What kind of protection is that? One that does not burn down the house but also does not protect transistors. That is effective protection? Real world surge protectors, such as Polyphaser, don't even discuss their products in application notes. Instead they discuss the most critical component of a surge protection 'system' - earth ground. Where does APC even mention earth ground? Where does APC even ask the homeowner to verify that most critical 'system' component? You have the paperwork. Where do they discuss earthing - the component that even Franklin demonstrated in 1752? APC is mute because they don't claim protection from that type of surge - the surge that destroys transistors. Missing statement from APC means they don't even claim that protection. You know a surge protector is not effective IF 1) it has no dedicated connection to earth ground or 2) it avoids all discussion about earthing. That APC is ineffective twice over - meets both criteria for ineffective protector. Its called lying by telling half truths. They make ambiguous statements because they don't claim protection from surges that damaged electronics. Where are the specs - with numbers - that claim common mode surge protection? Real world protectors provide those numbers. Back to same concept - why lightning struck that pond is also why Franklin demonstrated effective protection. Same protection so well proven that your local phone company, connected to overhead wires everywhere, need not shutdown phone service for thunderstorms. All use the most critical component in lightning protection. Be it a lightning rod over the pond or a surge protector - effective protection is about earthing a surge, which that APC UPS does not do and avoids mentioning. A surge protector is only as effective as its earth ground. Polyphaser, an industry benchmark, discusses earthing extensively in application notes. Where did APC even mention the word 'earth' even once? Where do they put numbers to their claims. Where do they even specify which industry standards? They meet the standard that says the surge protector will not kill you - human protection. Where is the claim for transistor protection?. No earth ground means no effective protection - as was well proven even in 1930s research papers. One electronic device essential to ponds and easily destroyed by surges is that GFCI. Just another reason why 'whole house' protector is important and why a lightning rod over that pond might be considered (depending on the frequency of CG lightning).
