Isn't this what a surge protector is for?
- bayindirh 2y agoYes. In most cases, assuming you live in a 220V country, a surge protector will absorb the upwards spike, and the voltage range (a universal PSU can go as low as 107V) will handle the brownout voltage dip.
- Kerb_ 2y agoPretty sure surge protectors are less effective against dips than they are spikes
- acstapleton 2y agoNothing is really going to protect you from a direct lightning strike. Lightning strikes are on the order of millions of volts and thousands of amps. It will arc between circuits that are close enough and it will raise the ground voltage by thousands of volts too. You basically need a lighting rod buried deep into the earth to prevent it hitting your house directly and then you’re still probably going to deal with fried electronics (but your house will survive). Surge protectors are for faulty power supplies and much milder transient events on the grid and maybe a lightning strike a mile or so away.
- Wowfunhappy 2y agoWould a UPS protect against that either, though?
- Kirby64 2y agoNo. Current will find a way. Lightning will destroy things you didn’t even think would be possible to destroy.
- Wowfunhappy 2y agoSo I'm still left with int0x29's original question: "Isn't this [an electricity spike that a UPS could protect against] what a surge protector is for?"
