Today, each of us at home has equipment that is sensitive to the stability and quality of the electrical signal. These are refrigerators, computers, televisions, microwave ovens and much more. If we conduct a brief analysis of the quality of electrical networks, we can draw certain conclusions. And you don't even have to be an expert. Here it is already clear that the nominal deviation from 220V is more than permissible. And the permissible, we note, is only plus / minus 10V. That is 210-230V. Let's talk with you about how to choose a 220V voltage stabilizer for your home and protect your equipment from damage.
General information
As noted above, the quality of the power grid is really not encouraging. But everything would be fine in good weather, when the voltage in the outlet is more or less stable. The most miracles begin in a strong wind. Then there is a chance to observe the voltage and 150V and 280V. All this can lead to the fact that your refrigerator, TV and other expensive equipment will burn out.technique.
To prevent this from happening, you need to use a voltage stabilizer. This is not such an expensive technique, but very necessary in our time. Any surge of electricity in the network will be stabilized. The worst thing that can happen is the stabilizer fuse will burn out, which costs no more than a few rubles. Agree, not the biggest loss.
The need for a stabilizer
It is worth noting that it is not so difficult to choose a 220V voltage stabilizer for a home. It is quite another thing that many are not going to do this. To understand whether you need such an acquisition or not, you do not need to think long. But blindly go and buy a stabilizer is also not worth it.
To dot all the "i", you need to take measurements. For this, special measuring equipment is used, which allows you to record the maximum and minimum power surges. So, if in general the network was stable, and the voltage did not go beyond 205-235 V, then the stabilizer is not vital. Although it is necessary to protect expensive and sensitive equipment, and this is a fact. If the measurements showed deviations of more than 10% in one direction or another, then you need to install protective equipment. Otherwise, any electronic device, be it a TV or a refrigerator, may fail. Believe me, repairs will be very expensive. Sometimes it is even better to buy new equipment than to repair the old one.
Single phase orthree-phase?
It's hard to say exactly why questions arise in this case. If you have a single-phase voltage in your room, and all household appliances are single-phase, then the stabilizer must be appropriate. A three-phase network is more often used in factories or offices. It is usually powered by electric motors, powerful air conditioners or pumps. In this case, it is permissible to use only a 3-phase stabilizer.
But it often happens that a 3-phase network is suitable for a house, and all the appliances used are single-phase. Which voltage stabilizer 220V to choose in this case, you ask. There is some room for optimization here. If each phase is loaded equally, then we install 3 single-phase stabilizers with equal power. If important household appliances are connected to one or two phases, then protective equipment is placed on them, and the last line can be connected directly.
Which voltage regulator 220V to choose for a summer residence
One of the most important things is the power of the protective equipment. In order to choose the right stabilizer, it is necessary to correctly calculate the total load of electrical appliances that will be connected to it. Each electronic device has a technical passport, where the power consumption is indicated. But do not forget about such an important parameter as starting power. For example, a household refrigerator has a power of 0.2 kW. At the same time, its multiplicity according to the passport is 5. It is necessary to multiply 0, 2x5, and wewe get the starting power, which in our case is 1 kW. Of course, sometimes we do not use several household appliances at the same time. In this case, the total load on the equipment will be an order of magnitude less. It is not recommended to overload the stabilizer, as the protection will work and it will not turn on until you disconnect one of the household appliances.
Always buy with power in reserve
It is not advisable to buy equipment back to back. For example, you do not know when it will be necessary to connect new equipment to the stabilizer. Imagine that there is 250V in the network, and you urgently need to complete a report on the work on the computer. But the stabilizer is occupied by other equipment that cannot be turned off. Power is also lacking. The situation is getting stalemate. It is for this simple reason that always take protective equipment with a power reserve of 20-30%.
Another important detail - the lower the voltage in the network, the lower the power of the stabilizer. For example, Shtil's 7kW protective equipment can withstand heavy loads. But the specific power, in our case it is 7 kW, is taken at the optimum voltage in the network of 220V. If this figure drops to 150V, then the power will drop to 4.8 kW. In principle, we have familiarized ourselves with the main parameters, now let's quickly go through the popular manufacturers.
Voltage stabilizer 220V for the house "Calm"
The Shtil company produces a wide range of protective equipment. A variety of stabilizers are available, ranging fromfrom low-power household to expensive office models. This domestic manufacturer has several undeniable advantages. First, the affordable cost of equipment. Compared to European models, the savings are about 10%.
Model "Calm" R 110 is used with a voltage range of 165-265V. At the same time, this unit boasts a stabilization of plus / minus 7%. This is unlikely to be suitable for sensitive electronic equipment. The price of such a unit is only 2,900 rubles. But the R 16000 with a power of 16kVA gives +/- 4% stabilization, which is already suitable for complex sensitive equipment. But such a unit costs 70,000 rubles. It is advisable to install it in offices where the total load on the network is high. In general, this is an excellent manufacturer. The build quality of the equipment is high, and at the same time its cost is quite affordable.
Products of Energia
You must have noticed that most attention is paid to the domestic manufacturer. The fact is that such a technique is in high demand for several reasons. The first is affordable cost, and the second is ease of maintenance and repair. Believe me, in case of any breakdown, it is much easier to find spare parts for the Calm or Energy stabilizer than for the European model.
As for this particular manufacturer, many consumers leave positive feedback. For example, a 220V voltage stabilizer for the Energia house SNVT-500/1 is in demand. It's protectiveequipment with a capacity of 0.5 kVA. Such a stabilizer is made specifically for connection to gas equipment. Most 2-circuit boilers have a huge amount of accurate and sensitive electronics that do not like even the slightest voltage drops. This unit is able to stabilize the voltage up to +/-3%. All this for 2,900 rubles. The company also offers more powerful models, such as APC-1000, 1500 and others. Choose equipment depending on the power, and everything will be in order.
What are consumers saying?
So you already know how to choose the right 220V voltage stabilizer for your home. Which one is better is hard to say. For example, for small loads and the connection of precise sensitive electronics, the Energy technique is excellent. If the load on the protective equipment is significant, but stabilization deviations within 8% are acceptable, then we can safely give preference to the "Calm" technique. Fortunately, today there is a choice, and quite a large one. If you do not trust the domestic manufacturer, then there are plenty of European stabilizers on our market. Most of them, especially German, Italian, etc., are of very high quality. But often there are problems with timely repairs, as spare parts are often delivered to order, and this is not too fast.
Conclusion
Here we come to the end of our article. During this time, we managed to figure out how to choose the right stabilizervoltage 220V for the house. The wall-mounted option, by the way, is very convenient. Many consumers are talking about this. The unit is installed on the wall using fasteners and does not take up space in the room. Otherwise, where such equipment will stand does not matter. Of course, we are now talking about houses and apartments, and not offices and industrial buildings, where the weight of the stabilizer can exceed 100 kilograms. In general, this is all that can be said on this topic. Calculate the total load, decide on the manufacturer and make a purchase. Only in this way can you reliably protect your electronics from damage due to power surges in the network.
