from my personal experience I got a couple of cordless phones fried by lightning presumably through telephone line, or could be from high voltage surge through tenaga power line, now no more lightning problem after installing lightning isolation devices at both telephone line and power line

an interesting read on lightning protection in easy to read plain english according to above IEEE paper, plug-in protector+building earth does work in protecting home appliances! Tenaga and telekom lightning protection system do not provide 100% lightning protection to home appliances check out this forum, the same westom? http://forums.anandtech.com/showthread.php?t=2334015 This post has been edited by neb: Mar 5 2014, 02:24 PM |
