We have a couple of flat panel TV's, computers, and other electronic devices connected to various surge protectors. Recently we've heard that surge protectors lose their ability to protect against surges over time. The theory goes that each time a surge protector protects against a surge it loses some of its ability to protect against surges. Eventually, the protection is completely gone and you are left with a power strip with no surge protection.
So my questions:
1. Is this true?
2. If so, how can one tell if a surge protector still provides sufficient protection?
3. Is there anything in particular one should look for in a surge protector for any given application? I don't follow the Joule ratings, etc.
4. Are today's devices (I'm thinking of our plasma TV, and LCD TV, Wii, and home theater in particular) better protected by a UPS, where the battery provides a more stable power supply? I'm not interested in protection against power outages per se, just looking for the best protection for these devices. Given how much they cost relative to a UPS, it seems like cheap insurance, but is it overkill?
