Take note that the SPD is max at 40ka
Would recommend at least 80 ka

How much the cost..how they http://www.lightningsurgeprotectionmalaysia.com make the calculation? based on power socket or how? or number of fuse in the DB?

Beside Tokai, Pekat teknologi is another competent contractor. Basically they use similar products i.e. furse, novaris and approved equivalent.....

I used Pekat Teknologi to install Surge Protection and Lightning Protection for Setia Eco Park home as the home (3 storey high with lift) is higher than the 2 storey homes nearby. Expensive but with lightning flashing around during thunderstorms ... (Weather is not like when I was a young man. Nowadays heavier rains and frequent close-by lightning strikes.)

hebronep - So far, any problems....any damage incurred? I think the weather is the same lah. Just that nowadays we have more sensitive equipment that are prone to surge damage. Last time, we still swim naked in river or ex-ming pool despite thunder clapping kau kau...or we are still playing bola sepak lumpur till dusk ro gelap. tongue.gif

Theorectically, yearly maintenance is required to verify the earthing conductivity, continuity of the Faraday cage (from top to ground) and also to check on the SPD......This may cost some money.

No problems so far ( 3+ years). I also installed a lighting monitor (on-top of copper cable from roof to ground copper rods) which reads how many direct lightning strike on the home. I will read next time I am in Eco Park home.

Surge protection will filter out all the power line communication signals. No use to use power line communications if you intend to install surge
protection. Better to position the wireless router in optimum location such that reasonable signals can be received in all parts of the home.

hmmm..lightning counter is good for lightning. this little device clamped onto the copper tape may not read surge attack...but good to have...

The pricig of the SPD based on:
1) maximum surge current needed- 20/40/60/80/100/120/150kA
2) classification of surge protection- class 1/2/3
3) Brand- price varies very much with different brand and technology
4) single phase or 3 phase power line.

Usually the price range from RM400-RM2500, depending on the selection of the above criterias.

big or small house doesn't matter.
Electricity consumption doesnt matter.

If FOC, ok la...the blu/test button is on the ELCB (Earth Leak Circuit Breaker). Recommended to push the button monthly to ensure that the eLCB turns off. If you press the button and the elcb does not cut off, time to change a new one.

we should go for Greater kA or the smaller kA in the SPD ?

Learn what an effective SPD does? This was first demonstrated by Franklin in 1752.

Lightning (and other surges) seeks earth ground. A best connection to earth is via a wooden church steeple. Because wood is a better electrical conductor than air. Unfortunately, wood is a poor conductor. So a 20,000 amp lightning strike would create a high voltage. 20,000 amps times a high voltage is high energy. Church steeple damaged.

Franklin connected lightning to earth via a better conductor - often called a lightning rod. That conductor is a better conductor. So a 20,000 amp lightning strike creates a near zero voltage. 20,000 amps times a near zero voltage is near zero energy. No damage.

That is protection of a structure. We do same to protect appliances.

Lightning seeks earth ground. A best connection to earth is via appliances. Unfortunately appliances are poor conductors. So a massive current would create a high voltage inside the appliance. That high current times a resulting high voltage is high energy. Appliance damaged.

For over 100 years, informed consumers connected lightning to earth via a better conductor. Usually a direct hardwire connection. Otherwise a next best solution is implements: a 'whole house' protector. Then 20,000 amps connected low impedance (ie 'less than 3 meters') to earth creates a near zero voltage. The resulting near zero voltage means no energy dissipates destructively in appliances. No appliance damaged.

A protector adjacent to the appliance does not do this. The protector at the service entrance must be sized to connect even direct lightning strikes to earth. And not fail. So a minimal 'whole house' protector is 50,000 amps. If a surge damaged that protector, then a 100,000 amp protector is needed in that venue.

Described is what effective protectors work, why they work, and relevant numbers such as 50,000 amps. Because any protector that fails did not provide effective protection. Protectors must not fail even after many direct lightning strikes.

What should also be obvious is what is more important than a protector. Protection is defined by the quality and connection to earth ground. Both for structure protection and for appliance protection. Most of your attention should focus on THE most important component in every protection 'system': earth ground. Since that is always where hundreds of thousands of joules harmlessly dissipate.
