As a retire audio tech, I saw my share of lighting damage over the years. Unplugging is the ONLY way to totally protect your equipment, and that includes internet cable and any type antenna cables. Those also create a path to ground, and if connected, can be a source for damage.
lightning storm
listening to my new Maria Callas vinyl last night and a huge thunderstorm/lightning storm starts up. About 2,3 seconds before each boom, I was getting a lot of static through my speakers. EMI from the lightning? I have no idea so asking the group. Thanks. Smart ass answers accepted also :-)

HAHA π π . Be careful with that back around 1998 when the strip protectors weren't so good a lightening storm fryed the transformer in my Kenwood receiver and no parts available so it was done. I did find a replacement on eBay for $475 I think it was. Get one of those big ones that the whole thing plugs into the wall , no cord at home Depot they have a $10,000 protection guarantee. |
I donβt think the damage was caused by EMI. More likely from an electromagnetic pulse (EMP).
Edit: I ran across this device on the Net. Does it really work? EMP & Lightning Protection for Vehicles (DC-12V-W) . |
The Internet is filled with stories about lightning coming in via the cable modem and taking out entire HT systems via burned out Ethernet ports. Most Internet users rely 100% on Wifi, but for those of us who use it professionally or just donβt like to have Wifi problems we wire all our big gear up. Our work computer, TV, music streamer, etc. and so I take a paranoid approach. Using Ethernet is great for reliability but also leaves us more exposed to incoming surges. I use an external coaxial surge protector with gas discharge tube. Internally I air gap the modem and router with fiber/Ethernet converters and at the end of long runs I use Ethernet isolators (not surge protectors) which are tested to UL 60-601 |
