Surge Protector Lightning Strike Protection: Computer & Modem Safety During Storms

1-half of this damage can be avoided by applying the correct rules
execution of all leads / and distribution / electric -
mainly energetic - the house, building, etc.
2-Americans in simple sketches of installations entering the house
- on the wires / from the outside / they make such a few turns with the Cu wire and ground / lead to the nearest earth electrode /. The nearest - means making the earth electrode just below the place of introduction.
If only every cable coming from the outside had such a design
the inside of the house would be safer.
The 3-socket power strip of the equipment is pointless, they duplicate what is already in the equipment
there is security in power supplies. They are dangerous themselves - because
The power switch can burn - and sometimes the clasps fall off
metal - inside - make a short circuit.
4-in the case when the only expense for overvoltage protection - is about PLN 50 for a "surge voltage" strip - the results will be
unhappy.
5-unfortunately, overvoltage protection is not cheap in practical implementation, but you can slowly increase its level by collecting materials such as: how and what to do to make the overvoltage protection better and implement your plans step by step.

I saw the UPS after the lightning meeting - a pile of coal in the housing, and the computer survived, and the power supply in it, so there is some protection.

Probably the only and best security. After the shot, it will only seduce the UPS, but it is not a rule to follow. In my case, the old APC-600 has always been in front of computer hardware. It once struck a central hit on the street and smashed the UPS, not to mention how beautifully a 60W / 240V light bulb fired in the kitchen on the ceiling with sumptuous fireworks from the sockets. Amazing view but no wonder. The equipment withstood, and in the UPS the fuses, varistors and 8 transistors or sometimes some small things for good measure fell out. After the repair, he got a new life and this is already his 3.
At home, a 3-wire single-phase electrical installation, as in the old building, without a lightning protection system, but I just drove a 2m long steel loop into the ground and connected the pins from the sockets to it, because the washing machine "ligated" and after this treatment it stopped

@OldSkull: Somehow I can't remember anything too ordinary lucko [it's about a transformer ??] it fell. Probably nothing. There were contraptions behind the impulse power supplies (first, the power supplies themselves). Now, at the lightest sound of the storm, I practically turn off the electricity in the cottage. Fuses and some I2C memory cube fell in the CO furnace.
One lightning bolt in the pole cost me some 2 kPLN and it will still cost a new monitor (I'm now on a borrowed one).
I wonder if it would be possible to resuscitate this with burnt backlight. If I had the so-called a graphoscope, I would do a home theater, and yes, just remove the casing from the back and put a candle behind the monitor ...

Hello!
Earlier I was supposed to write but it was closed ..
Can I feel safe if I turn off the main circuit breaker during a storm? It seems to me that not because why the spark would not jump.
The second thing is if something hits the rope and goes to the house along the wires in the wall: do I have to replace the installation then?
And another kind of thing: I have radio internet. If the discharge goes along the antenna cable to the router, can it get to the electrical network at home?
