To completely protect your house you will need two levels of protection however if you plan on implementing it you would be spending A LOT of money.tharinda07 said:machan ube surge protectors 3way ,response time eka micro sec2 ewada?
mulu geatama hay karana surge protectors ganna thenak dannawada?and hw much?
Level 1
A surge protection stage that is able to handle massive surges installed normally at the service panel (breaker box). This is done using GDT (Gas Discharge Tubes) and Inductors. This level does not whip out the surge but is intended to decrease the surge to normal levels (bringing down 100000V to 6000V). These have a responce time of around 6-10 nanoseconds
Level 2
A surge protection stage that is installed at the point of exit (ie. at the plug base, wall outlet). And is able to handle surges that are generated from within the house as well as outside. These protectors use MOV's. These have a very fast responce time of <1 nanoseconds.
Also Level 2 MOV based surge protectors require a thermal fuse! There are few ones out there that only have a fuse. A surge protector without thermal fuse cut off's is a fire waiting to burn the house down.
Its better to make your own surge protectors in Sri Lanka. A 25K (25,000amp) protector will cost around Rs. 25,000. Belkin protectors from American Best Brands are far cheap though but still expencive compaired that the cost of make a 30,000amp protector at home is aprox. Rs. 200.
Remember that Lightning has be reported to have around 200,000amps. So when going for surge protection spend as much as you can.
But still remember that an lightning striking near by will fry everything even if you have a surge protector this is because the EMP generated by lightning will over volt any metal object it touches (including the AC wires in your house, this is when the GFCI blows!
).GFCI = Ground Fault Circuit Interupter (Aka trip switch)
To answer the UPS question, The only way to know if your UPS can protect or not is to see the inside of the UPS. The PowerCenter UPS from Vence is 100% horrible, useless, pointless. However the Panora UPS seems to meet international standards. If you have PowerTree, PowerCenter from Vence or anyother cheap brand, kiss your PC good bye!
Why do I say this? Because UPS without a choke coil (inductor) is 100% open to high surges that cannot be supressed using a MOV or GDT. The inductor is the only device that will filter out this type of surges. I'm not sure about Prolink UPS's but I know, PowerTree, Sunpac, and all these other cheap UPS's will not protect your PC. Heck. The PowerTree I have with me doesn't even have a basic MOV!
