Let’s get one thing perfectly clear here. First, your title claims to be some kind of engineer. If true, then you always post supporting facts and numbers with each claim. You did not. When it comes to being condescending, you started it with ‘imperial decrees’. That insults me and any other educated people. I am assuming you did not understand that you were being condescending. Apparently you did not learn that recommendations must always include the reasons why. Otherwise the recommendation is akin to a scam.
I hope we can put an end to these sort of insults. Simply saying why - so that the opst can be based in honesty.
Now, back to science. Having now posted your reasons why says why you do not get it. For example, a million volts is everywhere in a connection from cloud the earth? That violates how electricity works. There can be a million volts between point A and B. That means that same million volts does not exist between B and C. Voltage only exists between two points. But in myths, that same million volts is in every location A B C D, etc. Your description of lightning explains why you do not understand how protection works.
You also do not understand joules. How do hundreds of joules in a protector absorb surges that are hundreds of thousands of joules. How does a power strip protector stop what three miles of sky could not? It does not claim any protection in its numeric specs - what the informed look at - the numbers. Joules - IOW where hundreds of thousands of joules dissipate. That is what you should be discussing.
Return to science we all learned in primary school. Lightning seeks earth ground. So lightning took a best path to earth via something more conductive than air. A wooden church steeple. Yes, wood is an electrical conductor.
But wood is not a very good electrical conductor. 20,000 amps through wood creates a very high voltage. 20,000 amps times a very high voltage is high power. Church steeple is destroyed. Excessive joules absorbed by wood.
Franklin put a lightning rod on the church steeple. Does a lightning rod provide protection? Of course not. A lightning rod simply connects to what does all protection - earth ground. Some foolishly argue pointed verse blunt rods. Trivial and irrelevant. What makes a lightning rod effective? Better earthing. What does the protection? What everyone forgets because they cannot see it? Earthing electrodes. How to make a lightning rod more effective? Enhance its earthing.
Now, the same 20,000 amps has a conductive wire and ground rods. 20,000 amps through wire and earth ground rod creates only a tiny voltage. 20,000 amps times a tiny voltage is tiny power. Near zero joules absorbed by the rod, wire, and church. No damage.
Protection is always about where energy dissipates. Always.
What is the connection from cloud to earth? Lightning to utility wires down the street is a direct strike to every household appliance. Damage occurs when a homeowner all but invites lightning inside. Once that energy is inside, then nothing can stop a destructive hunt for earth. Nothing can stop the hunt.
Protection means that energy does not enter. Lightning that finds earth via 2 x 4s causes house damage. Protection means a lightning rod. Lightning that finds earth via a computer, dishwasher, or furnace causes appliance damage. Protection means every incoming wire connects directly to earth at the service entrance. A short (ie ‘less than 10 feet’) connection via a ‘whole house’ protector.
Return to Franklin’s lightning rod. Where are those millions of volts? Where are those hundreds of thousands of joules? In the sky. In earth. Not in Franklin’s lightning system. Where are hundreds of thousand of joules when a ‘whole house’ protector connects 20,000 amps to earth? In the sky. In the earth. Not in the protector. And not destructively inside a house.
Recommended with prejudice and decades of experience is earthing and a ‘whole house’ protector. What is found in every building that can never suffer damage. As any honest post does, also said is why - with numbers. Provided is what everyone learned in elementary school science. And what you should know before recommending any protection system.
Responsible homeowners know that every wire inside every incoming cable must connect short (ie ‘less than 10 feet’) to earth before entering a building. Low impedance is a critically important number.
The concepts were taught in junior high science. To have knowledge means a hypothesis based in well proven science (with numbers). And then experimental evidence (more than just observation). Without both, knowledge does not exist. Without numbers, well, that is the definition of junk science. Knowledge from observation is classic junk science.
Well, 911 emergency operators do not remove their headsets and leave the room with each thunderstorm. Orange County FL was suffering lightning damage. So what was done to eliminate damage and danger? Orange County upgraded what does protection: earth ground. We know direct lightning strikes without damage is routine. But only when humans learn from their mistakes. And fix the earthing:
Routine is it have direct lighting strikes without anyone even knowing the surge existed. Even a protector must remain undamaged. But that means learning the underlying science and numbers. The always required reasons why – which are provided here.
