I'm going to share with all u fellows who thinks :
1) I've never experienced a surge before. As long as i take all necessary precaution it will be safe
2) Yeah, i can never be so **** out of luck. Its not going to happen to me
3) I stay in a block of flats. So many units together, i cannot be so sway
Let me tell u, if u belong to any of the above 3, **** DOES HAPPEN!
Happened to me twice, once last year and another this year. During a severe thunderstorm last year (i only have a UPS w/surge for my room), the lightning took out
a) My wiireless AP in my living room
b) my living room 43" TV
c) 1xADSL filter
External of my unit:
a) Water Pump System
b) Intercom System
Neighbouring units all OK except mine. So, u think **** only happens ONCE, naw.. New intercom system installed with lightning strike protection system. In addition, i installed an additional Belkin Surge Protector (basic model) in front of it. What happened was the surge was so severe it took out the intercom system again and the arrestor was not quick / efficient enough to arrest the surge.
So, its up to u to believe how safe u your household equipment is when a severe lightning strikes direct or very near your home.
In such circumstances, u'll be glad u have the additional step down transformer to take the first hit rather than your iRobot power supply.
I think this perception of rare occurance happens mainly because many of us are not aware of it. Unless there's injury or loss of life, it'll not be reported in the news (unless its so freaky like the lone car at the carpark being struck by lightning!). In addition, with the majority staying in HDBs, even if there's common equipment damage, it'll be fixed by the maintenance team/town council. The unfortunate units struck by lightning isnt likely to go around door to door telling everyone of his plight. Probably just suck thumb and make good his own repairs.
I see, but that never really happen right? Never heard it happen before...
Even if such a thing happens, logically everything else in the house or block will kanna right?
