Surge protection devices are not always worth it. It is far better to have a decent grounded electrical supply to the residence - not always pssible ofcourse if you are renting or in some condos.
Surge protection is just as it says and is only partially effective at best. Grounding, although advisab;e for any applicance will make no difference to you PC or TV whatsoever. The mains power connects diretly to a power supply unit that converts the 150-220 Volt supply to the 3, 6 and 9 volts needed for the internals of the PC/TV.
What you really need here in Thailand is a UPS. This is in effect a battery that is constantly charged while plugged into the mains. The surges and voltage fluctiation is of no relevance and the AC supply is first convereted to DC to charge the battery and then the battery feeds a signal generator that poduce a clean 220/240 Volt 50/60 MHZ depending upon its settings. You then have the added benefit of knowing that you have enought ime to power off the PC sleanly in the event of a long powercut and short power cuts will have no effect whatsoever.
This really should alll be on the Digital Realm forum.
Guess
You are of course correct - however trying to get a decent UPS for domestic use here in Thailand is not always easy.
Try one of those small computer shops along Phetkasem road.
I bought mine in a shop close to Thai Farmers Bank, between Soi 68 and 70 I think. Not 100% sure if the address is correct, but it should be somewhere in that area.
Therre is a new computer shop in Nebkerhardt Road just North of the Dechanuchit crossroads. The have a 800va box for less than 2000 Baht. I was looking at it last week.
