When lightning hits....
Will it blow your modem, even if the phone line is NOT connected to it?
Will it make your answering machine act like it is on drugs? Will it short out a caller ID box? Will it cause an OPEN in in 1 line of a 4 conductor phone wire? Will it losen the ground clamp from the phone wire gnd to the electrical wire GND ? Any thoughts from those who know?

Dave,
Check out http://www.nationalgeographic.com/lightning/2.html There are a few errors, but the essence is there. You'll have current in the hundreds of thousands of Amperes. Nothing is sacred. Anything can be fried (or spared). My neighbor's house was hit probably 10 or 15 years ago; she showed me the light bulb that the bolt left/entered into. There is a nice hole (no sharp edges, very round and smooth edges) in the bulb. It burned out motors in her house. Quite a mess. She felt her hair stand on edge when she was lying down on her couch and the bolt struck. Not pleasant. 73 from Rochester, NY Jim "Dave or Debby" wrote in message ...

First appreciate what Franklin taught us in 1752. Lightning
seeks earth ground. Franklin demonstrated how to keep lightning from seeking earth through church steeples. He gave lightning a better, electrically shorter path to earth. We call them lightning rods. However the rods really are not protection. It is just that we humans tend to associate what we see with the solution. Those lightning rods were only as effective as their earth ground. And that is the point. Protection from a direct lightning strike is defined by the most critical component of a protection 'system' - earth ground. Today we give lightning many more paths to earth. Antenna and utility wires. The most common source of a direct lightning strike to a building is AC electric. Lightning seeks earth ground. The shortest path to earth may be on AC wire down the block, into your house, through houshold appliances (destructively), to earth ground. Just a Franklin demonstrated, damage from a direct lighting strike is avoided IF it is earthed before it can enter a building. CATV and satellite dish wires are suppose to provide that protection. They are suppose to connect to central earth ground before wire enters building. This is required by code for human safety. It just also provides direct strike lightning protection - if earth ground is properly installed. AC electric and phone wires cannot connect to earth directly. So they make a connection to earth during the surge via a surge protector. Again, the surge must be earthed before it enters the building which is why telcos install such protectors, for free, at the service entrance. However the source of most destructive surges is also the one utility that has no earth ground connection. AC electric is the most common source of surges. And yet effective 'whole house' protectors can be purchased for about $1 per protected appliance. Again, the surge protector really is not protection. It is just that we humans tend to associate what we see with the solution. The protector is made effective by the surge protection it connects to - earth ground. All this assumes the most critical component of a surge protection 'system' exists. That means homes must meet and typically should exceed post 1990 NEC requirements. The NEC required ground should also be central earth ground to which all incoming utilities connect. Antennas also must be earthed for surge protection AND to meet NEC requirements. A direct ground from antenna to earth must be installed as required by human safety specifications of the NEC (National Electrical Code). Also the antenna wire should have some direct and short (less than 10 foot) connection to central earth ground where it enters a building. Damage from direct strikes to antennas also made redundant by the quality of that earth ground and connection to it. Surge protectors are simple science. They are not always required since some incoming wires can be connected to earth ground without surge protectors. Either way, the effectiveness of protection is defined by that central earth ground. This art is discussed in two thread in the newsgroup misc.rural entitled: Storm and Lightning damage in the country 28 Jul 2002 Lightning Nightmares!! 10 Aug 2002 http://tinyurl.com/ghgv or http://tinyurl.com/ghgm Many have posted misconceptions or irrelevant information. For example, the surge from a direct strike is a radio frequency transient - not some DC voltage. Connection to central earth ground must be short (less than 10 feet), direct, and independent because transient is RF. Details described in that misc.rural discussion. As you read this, that other newsgroup, and other posts, always remember this fundamental point. A surge protector is only as effective as its earth ground. Earthing is so critical that any surge protector not discussing earthing is not effective and often sold using urban myth or junk science reasoning. Furthermore, effective surge protection has been repeated proven effective since the 1930 meaning that surge damage is directly traceable to human failure.

if the flow of electrons goes from negative to positive in the real world........does lightning go from the ground up or the clouds to the ground..????? that is the learning question for the pile today......... First the cloud sends a leader to the ground then the earth fires back a hugh bolt to equalise the difference of potential. well tesla said that it went from the earth to the sky.........seems funny but i can understand the electrical theory of it......also he could prove it....he built lightning machines and he said he could get it to 'strike' anywhere he wanted it to..........maybe it would be useful if we set one of those machines outside bill clinton's house..........that would be nice............. |
Dave or Debby wrote: Will it blow your modem, even if the phone line is NOT connected to it? It can. Will it make your answering machine act like it is on drugs? It's possible. Will it short out a caller ID box? Maybe. Will it cause an OPEN in in 1 line of a 4 conductor phone wire? Again, possible. Will it losen the ground clamp from the phone wire gnd to the electrical wire GND ? If the ground line clamp got hot enough, and it was a direct strike, you bet your ass.

The tower was right next to the house and a chain link fence that circled the yard and was grounded quite well. The lightning hit the tower, went into the aluminum siding (which got loosened up badly along certain areas), made a beatiful arc of 3 inches or so between the siding and where the fence post for the yard started. When it ran along the fence, it blew off all the post caps and welded the gate and car gate shut. It blew a hole 2 feet deep and 1 foot wide in the ground where it stopped in the corner of the yard. In the house was even more fun. It killed most everything plugged in, even blowing the plugs out of the sockets completely along a couple circuits. I lived in the same town and thought a bomb had gone off. It was an early Sunday morn and even miles away was wakened in a hurry. I got over there about 20 minutes after the fact and was surprised to see the hole in the corner of the yard still smoking just a wee bit. There was even a bit of that glass that lightning makes (i forget the name). Needless to say, they thought a plane hit the house or something. Makes you wonder how many house fires were started by aluminum siding, antennae, and lightning. |

I believe I've read that "streamers" go up and there are a number of quick
strikes before the big show. Best bet is do a google search on lightning and see what turns up. I haven't ever worked with the stuff (thank heavens!) :) Of course, if anyone is in the way of it - does it matter if it goes up or down? BTW there was an article in the newspaper in the last week or so - some guy finally came home from extensive rehabilitation. He still is far from normal. He was a boy scout and a tree was hit near where he was standing. This occurred in the late 1990s and he just came home within the last two weeks! 73 from Rochester, NY Jim " --- Outgoing mail is certified Virus Free.

How a plasma wire is constructed and how lightning currents
flow are two completely different events - happen at different times during a CG lightning event. How a streamer is built has nothing to do with the OPs original question. Lightning, as his question asks, is not going one direction. Lightning is a powerful RF wave. IOW it goes both directions. BTW powerful but typically not that much energy at a strike location.

What illegal towers? I hope you don't think amateurs are limited to 60 feet
or something. There are no 2 meter CB amps. My guess is that most amateurs run 100 to 150 watts on HF and anywhere from 5 watts to perhaps 70 watts on 2 meters. That is *plenty* for worldwide communications on HF and sufficient for a couple of hundred miles of continuous 24/7 coverage on 2 meters (depending upon mode/antenna etc.) 73 from Rochester, NY Jim " --- Outgoing mail is certified Virus Free.

Turns out that the bottom of the cloud is negatively charged and usually is
the cause of cloud to earth strikes. The top of the cloud is positively charged and can strike 5 or 10 miles out away from the cloud. This means you can be struck even if you're 10 miles away from the cloud and think you're safe. Up or down? If you talk electron flow, it can be either way. The following I clipped from a website: The average lightning stroke has a peak electrical current of 30,000 amps. Extreme lightning discharges can reach 10 times that, while some discharges, especially those within a cloud, are only a few thousand amps. In terms more people are familiar with, the electricity flowing within a lightning bolt can reach 200 million volts. Combined with the high amperage, lightning has enough energy to kill instantly. So, 200 million volts at 30,000 (possibly 300,000) Amperes. So much for the shoot-outs LOL. 73 from Rochester, NY Jim --- Outgoing mail is certified Virus Free.

According to weather service, though the lightning is called "Cloud to Ground" - it is from the ground UP.... As to what all would happen in a strike, it depends. Our home was directly hit once, the lightning went up under an awning, blew out a porch light and went in that way. The CB and every thing else was ok.. The brand new TV set got smoked. So, go figure. I've never - even in my repair business history - have ever heard of "everything" getting zapped. As to HOW the items work or not after, depends on how it was affected, though usually, they won't work at all, if in through a "power" supply. While some folks feel a set struck by lightning is usually non repairable, that is not always true. I've seen, heard AND repaired sets or devices that were hit by lighting with great success. So, a lighting hit is not always a killer for electronics. I've seen as much if not more damage done by power surges from Electrical Lines as I have with lightning. So, YOU decide which is more damaging..... Actually, I"d bet Electrical surges are a better bet for probability, as you're always connected. However, due to our experience from the lightning strike of days gone by, when a storm is approaching, EVERYTHING in my home except the light bulbs, furnace, refrigerator is unplugged. The phone is left plugged in to the phone jack, but modems are unplugged from the computers. The only other lightning strike I sustained which was not a direct hit, was a preamp on a 2meter repeater receiver got burned out. The receiver was ok. The transmitter and all else checked out ok. Though my answers are not definite by any means, these are just my experiences and knowledge of the subject. C.L. |
