Great video, very educational. After the Greenwave filter+generator incident I recently commented about, I’ve been wondering how surge suppressors work and how they fail. I now know what fried thyristor smells like. Mmmmmmm fried thyristor. 🙂
I have five that fried and became open circuits. Some others that smelled fried but are still working. I understand after watching this that those should be replaced too . I just received a few replacements (amazon is so slow this time of year) and first got my office back up and running. The good news is devices in the office seem to all work so the surge suppressors did their job. Next step the family/TV room. Fingers crossed.
The product most often damaged by bad quality electricity are … light bulbs. I wonder that damaged LED light bulbs can still work as DE filter?
Surge protectors was popular in 80s and 90s when CRT monitors were conected to PC central unit and computers costs 1000 dolars. Nowadays we live in cheap electronics from China universe but we don’t use surge protectors anymore. Maybe quality of electricity in big cities are better than in province???
I noticed that one-dollar shops sells cheap 1 watt neon night lamp. I wonder does it could be used as cheap dirty electricity filter.
I opened a bunch of fried surge protectors and they all had one way screws as well. An automatic center punch to make two indentations in the smooth/curved parts of the screw head and a snake-eye spanner bit quickly did the trick every time.
As for why these screws are used in the first place probably has nothing to do with protecting the little intellectual property inside. In North America these devices typically come with a large $$$ connected equipment warranty. An attempt to fraudulently get a damaged electronic gizmo refunded by tampering with and blaming the unrelated surge protector would be exposed by the scratched one-way screws and surrounding plastic.
Aha! That makes more sense.
