Couldn't find a thread about this.

My house is quite old and is on high land and very prone to lightning strikes.
Anyone can recommend a good and reasonable lightning arrester contact? Based in Klang Valley.

Care to explain how to do that and where to get thick copper? laugh.gif

I do have lightning arrester in my house. It was build in the 1970s and have been update about 10 years ago.
My house TV, washing machine, astro, computer, microwave have all been strike by lightning before. Modem strike until dowan to strike edi. Insurance also lazy layan us and I'm pretty fed up with having to off PC and modem everytime there's heavy rain, especially these few days.

You need to identify where the lightning travel from? Is it from your house or from incoming power grid? If from your house you need to install the antena that run the copper down to few feet under the earth. If from power grid you log complain to tnb that is all you can do.

You can try cal-lab lightning isolater, is much better than many lightning arrestor. Also another good option is use unifi as is fiber yout risk of frying the modem is reduce to one source (power only)

This is some thing interesting as I was also looking for protection against lightning damage.

How is Cal-lab vs Belkin in terms of protection against lightning strike?
We are talking about lightning strike and not power surge (from TNB) smile.gif

Was looking at this ABB product. Anyone used it before & comments?

I got a quote from these guys:

http://www.lpsystem.com/

Recommended by PJusa who has it installed as discussed here:

http://forum.lowyat.net/index.php?showtopi...37&hl=lightning

If there's no new recommendation, I will install it in a couple of weeks time. smile.gif

Apparently, TVSS is very expensive, and usually only used in light industry............. that's what I've been told when I called up another TVSS salesman. He recommended me to buy those plug point surge protectors as he is also using that at home. He said TVSS is overkill for a house. I think I can trust the salesman la, since he's not getting a sale and recommending me to get something else! haha.

Belkin and Cal-lab work difference. Cal-lab is isolating, where Belkin is to block the high voltage going in. I use both.

Cal-Lab, it usually fry the unit itself, and you need to pay RM 25 to the authorized supplier they will do one to one change.

I fried 2 cal-lab before, and all my modem and routers are saved.

I got a free Belkin, It do fried device, but risk are lower compare to without any protection. Need to go to their office and claim the warranty, they pay you back the modem too but to certain amount, If large amount need sometime to claim.

I've not heard of lightning isolater. Guess I'm too outdated already.
The one I have at my house is in fact a lightning rod, very old one. Which goes all the way right into the ground.

I'm not sure where the lightning travel form and stuff, I remember some electrician say my house is within the lightning path, whatever that means. And most of the time, my house electricity will trip whenever there's very strong lightning. I've also remember there was a time where the lightning strike directly at my fuse box (inside my house) and left a black patch there. How do I find out where the lightning travel from?

Will consider the unifi option. As now have to remove telephone wire from modem everytime lightning as well. Thanks.

I'm lost with that. That's something installed in the house to prevent the electricity from going crazy due to lightning is it?

How much does Cal-lab cost roughly? I'm sure it's quoted based on house size. Any contact that I can get to give me a quotation?

If I not mistaken, you should place the lightning rod away from your house. That way, it will extract the lightning away from your house and travel to earth.

If you place the lightning rod ontop of your house, it extract the lightning to your house and down to earth. If you share the earth, that will go back to your electrical. If your earth don't share, your ground earth is too near to each other.Thousand of KV can anytime jump to your any home wire.

Near my taman, those lightning rod post place away from the house. The post at the edge of the house garden.

Not a must, just don't share the same earth. Say front for electrical earth, back of the house for lighting earth, and make sure copper to ground are thick and deep enough. Talk about earthing.. haha, the old school have Building earth, electrical earth, and lighting earth (rod).

Now only Electrical earth. Where is building earth?

The house is too small. Full of wire running around your house. Place the rod ontop, will let thousand of KV searching your wire to strike/jump over. And not forgetting the EM is can produce.

Now cost down era. Where got so many earth nowaday. Copper price now sweat.gif

Just imagine without lighting rod, it go into your house electric or water pipe. Especially when taking bath.

The Lighting rod will run from roof all the way down to the earth. Like the TS say, his house had this.

kamion,

PM25 should be fine for single phase. can also consider the higher grade ones if budget permits (i.e. can tahan a higher spike). they will also check your earth to make sure its good enough or did they do that already. if earth not good enough they will have to either hammer more copper rods in your existing earth (if connection and all is good) or install additional earth (=extra cost). they're pretty professionell though and i am happy with their product.

Zap his electrical may not be direct hit from lighting it maybe from power grid. Is best ask his neighbor, and ask expert to check.

Fix the lighting rod is a good start.

Any other Cal-Lab users here?

Just to make the air clear as i sees some of the post are miss guiding ppl here.

Lightning is same as electricity, they look for the easiest path to travel to ground. If your earthing system is done properly, lightning will travel to earth on its designated path without affecting other things under the building.

Lighting rod, if you all are talking about the needle place on top of the roof, that is called an air terminal. The air teminal is there to provide a point of strike in case the lightning decided to strike your house. without this, the lightning will strike any metal nearest to its reach. If you want to have the air terminal away from your house, make sure it is installed higher than the highest point of your house and have them surround your house.
Those that attract lightning are called helita pulsar(is also an air terminal), which i do not suggest to use.

Those rod hammered deep into the ground are called earthing rod. Copper rod are hammered into the ground, 1 length, 2 length,3 length.., still not enough, extend to other earth point, until the earthing level is acceptable (<10 ohms for building earth and < 1 ohms for electrical system) the lesses the ohms, the lesser the earth resistivity, which in turn, make the best path for the lightning to travel to earth instead of striking your electrical appliances.

TS, how long have you been in the house? If you want a permanent solution, suggest you to just get a lightning specialist to do soil test, have them suggest a proper earthing system.
Just to give you a hint, building on highland is a little difficult to deal with when talking about lightning. It is the nearest path for the lightning to pass through to go to earth, and hgihland soil is difficult to get a good earth reading, thus require addtional soil treatment.
Else, install a surge arrestor, and make sure you get a branded one instead of those china made. Replacing surge arrestor could be expensive

There are 3 keys to a premise lightning protection.

First you got to understand that the lightning rod(air terminal) is those metal pointing rod on the roof. They act as a protection against lightning strikes which damage the structure of your home and the safety of people standing in a certain radius around your home, by directing the lightning to strike on the rod and safely grounding it.
There's a few type of air terminal available in the market. Some come in weird looking shape like a helmet with a point in the center, a ball shape, the shape of a brush and the traditional type, just a normal pointing copper rod. And each has its own function such as making the lightning to strike on the rod or diverting the lightning to strike somewhere else.

As what pky said, it is very important to make sure your electrician do the grounding properly by making sure the resistance level is less than 10ohm so that the lightning can travel down to the ground safely.

Second is SPD (surge protection device). These device come in many size and shape, and have its rating to how much kA(peek surge current) it can resist. The higher the kA it can handle, the higher your electrical appliances are protected. But be reminded that, the SPD can also get damaged by multiple strikes over the years, and you may have to replace the internal parts. Its something similar to cal-lab, but cal-lab is something small. Normally, SPD are installed next to your DB or inside your DB. This ensure that, all socket points are protected.

Third, is grounding or some call it earthing These are copper rods planted in the ground. A proper house earthing makes sure that any leaked current or surges will be channel properly down to the ground. Normally, you can see the rod inside a grounding pit outside the house. The pit looks something like this.

Now, im no expert, but i learn this all because im investing in a lightning protection for my house since i've been getting multiple surges and multiple damages to my electrical appliances.
Im paying around RM5000 just of the equipment and not included with installation.

Just to share with you. So far, i know only 3 companies doing lightning protection. You could call them up or meet up with them if you want to understand more about these things.

http://www.alltec.com.my/index.php - im buying their product. not that expensive compared to gltm.
http://www.gltm.com.my/ - pretty expensive since their using eritech products.
http://www.lpsystem.com/ - gave them a visit, but the office was closed.

Thank you so much for explaining. That has cleared up a lot of questions in my mind.

I'm only 20+ but this house is bought by my parents and they bought the house from another owner and have been living here for the past 40+ years, the house is probably around 50-60 years old.
And yes I'm looking for a permanent solution. What you've suggested is what I'm looking for exactly. I want someone to come to my house and suggest me a good, proper and permanent solution to this lightning problem. Where do I find a lightning specialist? Will the lightning protection companies provide specialists to test the soil if I request them to?

Thank you for your explanation and the contacts as well. I'll give them a call soon. Still have lots of read up on.

Just had LPS come install their Surge Protection Device.

In the end, went for the higher capacity one, as I told the salesperson that my house is one of 3 terraces in a row. Not really sure what's the logic behind this, but he recommended going one capacity up from the basic. So I installed their PM40-240 (RM610 inc installation) instead of the PM25-240 (RM470 inc installation).

They just connect in the SPD in parallel with the incoming supply, drill a hole through the side of your DB box to pull the wires through and install another small box next to it.

Any prove indicated it provided more stable current? Any capture before and after installed the device?
* Touch word...what if something still happen after installed it?

it doesn't stabilize the current, its a surge suppressor.
There's an indicator light on the device, typically, green light means the device is working, red means the device need replacement, have to check this status frequently to ensure the suppressor is working.
If something still happen, change to better suppressor or consider the possibility that the surge originate from some other source.

Just had LPS come install their Surge Protection Device.

In the end, went for the higher capacity one, as I told the salesperson that my house is one of 3 terraces in a row. Not really sure what's the logic behind this, but he recommended going one capacity up from the basic. So I installed their PM40-240 (RM610 inc installation) instead of the PM25-240 (RM470 inc installation).

They just connect in the SPD in parallel with the incoming supply, drill a hole through the side of your DB box to pull the wires through and install another small box next to it.

Bro, I'm not sure if i missed it or not, I doesn't seems to find any earth cable connecting the earth bar to EARTH. the SPD won't function without a proper earth. From the partial DB u posted, i believe there's a red cable connected to the neutral bar right?

Does it mean that if we get this device installed, don't need those individual Belkin/ Cal-Lab units to protect individual equipments in the whole house?

After pay RM610, this no guarantee will work? Than need to change to another suppressor and pay again?

Yeah, I was wondering that too................ The installer didn't bring the correct meter to test the earth, apparently. Instead, he just measured voltage across from incoming Live to the earth bar (250V), and across Neutral to earth bar (0.6V). He said this shows it's good enough. rclxub.gif

My electrician told me that the earth is properly connected already. Perhaps I need to get him to show it to me where he's connected it back to the supply earth. Here's a pic of the incoming supply at the electricity meter, which one is the supply earth?

Your picture show only Live(longer box) and Neutral(shorter box).

The earth is inside your DB box which is green wire all connect to a copper bar. Open the white cover and you can see it.

So what is the earth copper bar connected to? I don't believe I have a earth rod installed in my house, and it didn't seem like there was any wire connected to the earth copper bar to anywhere outside the DB box.

There is an earth wire green connect to the bar and go out(in the wall) to the garden earth box. Inside the box, there is a rod with the earth wire.

For new house you can see the earth black plastic box in the garden. While some already cover with the soil or grass.

If he did the test u described, then the earth bar definitely is grounded, not sure through where, but definitely grounded.

You have to understand, when comes to electricity, not all protection system is fail proof, but having 1 protection system is better then nothing.

Since I've installed the SPD, my DB hasn't tripped a single time with all the lightning storms happening daily.

Is it psychological, or have I just been lucky for the past few thunderstorms? It used to trip quite often with the daily afternoon thunderstorms.

I'm sitting here with my laptop on battery just in case. tongue.gif

Hi kamion,

Any feedback recently? Totally no more power trips?

Btw, my house's reading is 27ohms.
Which is quite high! The house is a corner unit with a very large and tall tree just outside my fence.
Cannot chop it down coz it is MPPJ's but my neigbour secretly killed the tree in front of thier house and was chopped down by the authority coz it was dead.

Thank you so much for explaining. That has cleared up a lot of questions in my mind.

I'm only 20+ but this house is bought by my parents and they bought the house from another owner and have been living here for the past 40+ years, the house is probably around 50-60 years old.
And yes I'm looking for a permanent solution. What you've suggested is what I'm looking for exactly. I want someone to come to my house and suggest me a good, proper and permanent solution to this lightning problem. Where do I find a lightning specialist? Will the lightning protection companies provide specialists to test the soil if I request them to?
Thank you for your explanation and the contacts as well. I'll give them a call soon. Still have lots of read up on.
I assume you too are very fed up with having to change all the electrical appliances in your house due to lightning. sad.gif

Hi munkeyflo,

Did you get any system installed yet? Any feedback?

Thanks!

Hi SeraphimGecko, yeah, it's been a couple weeks now, and the DB box has not tripped at all. I still can't say for sure if it's down to the SPD because I'm no expert. tongue.gif

Why must you kill the tree? It's so nice to have big trees outside my house, and this is only possible in mature housing areas. To me, the trees add a lot to the feel of a place and makes it feel so calm and relaxing when the wind blows through the leaves. Of course it adds shade from the sun too! cool2.gif

Hey there,
My electrician came to repair my fuse box the other day as the lightning was very bad and my whole hall was filled with smoke. The whole house was so smelly and half of the electricity was out due to the lightning strike at my fuse box.

So we consulted him about the lightning arrestor problem and he arrange for some lightning arrestor to be installed in our fuse box. He said the original 30-years-old ancient lightning arrestor is still usable while we do not have an arrestor in our fuse box or something. So paid over a thousand to install it. I didn't exactly follow up cause I was busy so my dad settled everything. But I'm still afraid lightning will strike again. sad.gif Guess it'll be alright for now as lightning not as bad these days in my area.

well, I like the tree too but it is giving me tons of presents everyday ( aka dried leaves ) and according to the electrician/specialist, the tall tree is possibly on of the reasons the lightning is attracted to. Anyway, no plans to kill the tree at the moment.
