You may recall that I was planning to make and market a new product, for details see http://www.cyprus44.com/forums/32812.asp



It is now on the market and can be obtained through Tektan in Girne or direct from me. As predicted the sale price is 100 TL including VAT. I will try to post a photo later on. It can be plugged into any socket and will protect the whole house.



I took a sample to the Chamber of Electrical Engineers and they were really very enthusiastic about it. They promised to carry out full tests on it on Monday 26th April. Of course I have done all the tests myself and I am very confident that it works properly and safely.



As far as I am concerned this is a must for every house. It is like an insurance policy. It may never be required but when it does, it will save you lots of money. Instructions is available in English and Turkish but you must state which one when purchsing the gadget. Ask for ELKO Voltage Protection Relay or in Turkish "ELKO Voltaj Koruma Rölesi"

Link works, however, if this for every 3 point plug it will become very expensive. Would it not be possible to have one device connected to the main fuse box?

Oh Richhard, you plug it into any socket and it will protect the whole house. You do not have to connect it to anything, you simply plut it into any socket. If the voltage goes outside the set limits, it will trip the mains. As simple as that. As far as I am aware this is a first in the world.

Hi Ismet.



Can you give any info regarding using your new product in conjunction with an automatic generator.



PS. I use one of your devices already; Elko 13 AVS Micro. This is plugged in the power socket which then has an extension lead which powers, TV, DVD, Sat, PC, amp, etc. Works fine. Is this unit the same as your new one above, apart from the fact that it only controls what is plugged into it, and not the whole house?



Thanks

I have the limits set at 175-258 volts. Anything outside these limits means serious trouble. Of course they can be set individually to cater for any need. In my house the voltage is pretty steady around 240, so I can set it to 200-252 volts with no problem.

Texas,

The AVS (Automatic Voltage Switcher) can be set to a minimum and maximum voltage but not as accurately as the programmable digital voltmeter which is at the heart of my new gadget. The AVS will switch off the appliances connected to it if the voltage goes outside the set limits. The new gadget is not connected to any appliance.

The new gadget will work with your generator properly only if your earth trip (RCD Residual Current Device) is active while you have the generator on which I don't think so. Hence you must unplug the new gadget when using the generator. I have written this in the instructions.

AJ,

Very good question, I did not think of that. I must write something about it.

You must switch off everything and pull out all the plugs, then switch back on the mains and see if it will trip again. If it trips again you should really call an electrician to check it and lodge a complaint with Kib tek for too low or too high voltage. They must really do something about it. Anything outside 175-258 volts is not acceptable and will certainly damage your appliances if you use it as it is. If you are in a troublesome area, you can see how close you are to the limits and hence you know whether you are near the high or the low limit. If it all happens suddenly, its definitely a fault and you should wait a few minutes before switching the mains back on again.

Is there any indication on your device to say whether your unit has tripped the power?

All I am thinking about is that if the power is tripped for any other reason then how do people know?

AJ,

There is no indication. If the trip is due to a normail fault in the house, it will trip again even when the gadget is not plugged in. One improvement I can thinkof is a test button. However this will have to wait for a while.

and what happens when your rcd is faulty. lots of them are. no one ever checks them. if the rcd is faulty and the local earth stake is not providing a very good earth, the electricity that you are putting to ground in order to trip the rcd will actually be making any earthed metalic parts of the house LIVE. what have you done within your product to prevent this situation.

letty,

I have already thought about that. As far as I know faulty rcd's are very rare but if that is the case, the 330 ohm 1/2 watt resistor used to supply the trip current will go open circuit within a second no matter how badly the earth terminal is earthed. However the voltmeter will keep flushing to warn you that your rcd is faulty in case the voltage is outside the set limits. So its fail safe mode in this instance. We are all supposed to test the rcd's once a month but I do not know of anybody who does that. So this gadget will only help warn the users that the rcd is not working properly.

Ismet,



The UPS control software that I am running to monitor the power supply to my computer reports an input voltage in the range 258.2 - 259.4 and a steady output of 220 at 49.9 hz. OK I'm happy that my computer is protected. I also have another UPS protecting my TV, DVD, Satellite etc.



What does the high voltage mean to other appliances in my house? I gues I should I report the matter to KibTek? If so can you please give (in Turkish) a phrase that will give them a firm idea that I want them to resolve the matter.. I'll know when they tell me to 'Siktir Git' that I've hit the right button.



Obviously given the bandwidth that you new system is set to trip at I must resolve this before installing it as I will be for ever 'tripping the light fantastic'... ;¬(

Just let me know where you live and I will think up of something.



Groucho (msg. 21),

First of all make sure that your measurement is accurate enough. One way to do it is to buy one of my protectors and connect it to the mains through a unearthed plug or open the plug and take off the earth connection.

Once you are sure you can throw the book at them. If need be I can write a notice to them and threaten them with legal action. That will do the trick

I think cyprusairsoft was asking a general question as opposed to a personal question i.e. how do Kib-tek regulate the voltage to everyone's house?

My guess is that when local transformers are installed they are rated for the predicted load and if that load is nowhere near the prediction then that is when you are likely to have problems with a higher voltage than should be.

Now I see. 66/11KV or the new ones 132/11 KV transformers are supposed to have automatic tap changers to keep it at 11 KV.

Problem no.1: some of these automatic tap changers do not work properly.

Problem no. 2: Our nominal voltage is 240 volts +/- 6%. thus the output on the 240/415 volts can be adjusted to 255 volts if the line is too long and hopefully the people at the end of the line will complain less about too low voltages. However when combined with problem 1 above, the voltage near the transformer can go over 255 volts and thus it is dangerous. I have seen as high as 262 volts, phoned the area manager and he reduced it next morning.



They should really invest more money and have shorter lines and not allow over loading. Trouble is that most things are done by trial and error rather than serious calculations. Whoever shouts most gets his way.

Redwine,

elko voltage protector is to protect your appliances against a fault like a broken or loose neutral which may cause the voltage to rise to over 350 volts. However, it is NOT a Surge protrector or Surge Arrester as they are known. The Surge protectors act very quickly against very short spikes involving well over 500 volts and usually going into thousands. The effect of lightening for instance is to cause very short lived surges and Elko Voltage protectors do not protect you against such occurences.



msg. 34

Throttle,

It will trip the RCD which effectively disconnects the mains, thus it will protect the whole premises.

BTW, it can be used on a three phase installation too. simply plug it into any single phase socket and if anything goes wrong on that particular phase it will trip the lot. However ifg you wish you may plug one on each phase and thus you will be monitoring each phase separately.

Update.



Voltage in our office this morning at 8am - 255V!

Now running at about 246-248V.



First indications are that this device will protect domestic electronics/electrics from high/low voltage fluctuations without "nuisance" tripping.



Device can be seen in operation at Octopus Pools office near HSBC.

Vaughan,

Do you have he means to test it at the higher and lower limits? It should trip off the supply the moment it goes outside the set limits i.e. 175-258 volts. I tested them. 258 volts fine but trips off at 258.1 volt, no messing about

Do you want to borrow a Variac to check the calibration of the unit?

I've got an 8 Amp one hiding in my shed somewhere, it's not enclosed - so you'll have to make your own arrangements re. safety...

Just call by if you want to borrow it.

I agree that using a Variac is a valid way of checking the lower trip point but does yours provide more output than the input?

AJ,

I presume you are asking Keith if his variac can provide higher voltage than the input? I presume it would not qualify as a variac unless it did that, so the answer must be yes but of course Keith will give the definite answer. I had a variac which would give voltage from zero to 20% over the input. Of course it depended on the configuration of how you connected it.

Of course you can. Suppose you wish to set the upper limit to 261 volts, AH= 261/5=52.2

Use an unearthed socket when programming it and don't forget, the password is 503. So press "set" twice and thgen ener the password etc.

You shsould freally complain to Kibtek for supplying such a high voltage but better observe it first to make sure that it was not a one off situation.
