Rating of the best voltage stabilizers for home and summer cottages for 2020

A stabilizer is a device that normalizes the alternating current in the mains and adjusts its parameters in the event of voltage surges. It should be noted that in the Russian Federation, devices designed for normalization at 220V are in great demand.

With the help of these devices, breakdowns of electrical appliances at home or in the country are prevented. However, in order for the protection to be really good, you need to use exclusively high-quality and safe units. These are exactly what are considered in our rating of the best stabilizers for home and summer cottages for 2020.

What are power surges?

With power surges, one way or another, each of us faced. A sudden flicker of light, a sharp shutdown of household appliances, a sudden increase / decrease in the power of any household appliances - all these are voltage drops in the network. Formally, a "voltage surge" is a deviation from the relevant regulatory documentation for the quality of electrical energy supplied to the house.

Such phenomena are not at all harmless: they harm household appliances, disabling them, sometimes irrevocably. Agree, when a good washing machine or a new computer (on which archival documents were stored) orders to live long, the damage from the jump is obvious, large-scale and costs a very round sum.

In general, power outages are as follows:

• Voltage deviation. A change in the amplitude of the current that lasts more than a minute. It happens within the normal range (i.e., acceptable) and above the normal. Usually, a deviation of no more than 10% from normal is normal.
• Voltage fluctuations. An amplitude change that takes less than a minute. Fluctuations of 10% of the norm are acceptable. Above - no.
• Overvoltage (overvoltage). This is a strong excess of the current amplitude (usually more than 242V). This can last even less than a second, but it is this deviation that can lead to sad consequences.

Physically, the most dangerous leap is the last one. Devices and equipment receive excessive electrical load and, unable to "digest" it, fail.

Causes of power surges

Globally, all reasons are divided into external (that is, they occur regardless of the state of the network) and internal (the reason is the incorrect operation of the devices / group of devices themselves).

Very often, a power surge is caused by the simultaneous inclusion of several devices that consume high power into the network at once. This is especially felt in houses and apartments where the wiring is old. It physically does not withstand the load of modern household filling (which is already in almost every home) and either turns off, or gives first a sharp drop in the voltage in the network, and then - when any device is turned off - its sharp increase.

The most common external factor is the lack of stable operation at transformer substations. The fact is that many of these substations are outdated morally and physically. They are badly worn out and need to be replaced, but they are not always replaced on time. And over time, the load on them constantly increases, although initially they were not designed for such power. So the old transformers give voltage failures.

The technogenic factor of surges is elementary accidents on power lines. Humanity has not yet learned how to transmit electricity through the air, so it is delivered to homes by wires, which have very fragile and unreliable protection. Wire breaks, overlapping them, lightning strikes, fires - all this leads to unwanted surges in power consumers - our household appliances.

A specific but very serious problem in the network is a break in the neutral wire. The contacts of the neutral wire in the shield are weakened or damaged - and a sharp overvoltage occurs in the outlet powered by this system - any devices connected to this outlet will instantly burn out.

Not the most common, but common cause of surges is loosening in the grounding of the system. If it is violated, then excess voltage can go to the cases and external metal parts of the devices. In addition to the danger to humans, this failure is also characterized by power surges.

A rather commonplace reason for spikes is network congestion. There is always a network in a house or apartment. It can be lower (in old houses) or higher (in new ones), but it is always there. And there is always a risk of exceeding it. Especially considering the rapid acquisition of more and more powerful household appliances by the population.

It may also happen that a small building or a small residential building was demolished, and a much larger house or office was erected in its place. Comparison of the energy consumption of a small house and an office is obvious, but the network connected to the facility remains the same. Therefore, incidents in the form of overloads are obtained.

The human factor also affects voltage failures. Elementary defects when installing a transformer or poorly laid wiring can produce regular voltage surges.

Household appliances themselves can also be poorly assembled. Then the working device itself can give jumps and failures to the network. Very often this manifests itself in the form of the so-called. flicker. Usually, devices with heating give such jumps - a process, as is known from physics, that consumes the greatest amount of energy.

The locality factor affects if a new plant or a shopping and entertainment center is built next to a house or apartment, or in general any building that consumes a lot of electricity. The system of a new object can be connected to an existing system and then, even with filters and stabilizers, there will be jumps periodically.

The notorious hit of lightning in power lines gives sad consequences for them and end consumers. Even lightning protection is not able to completely eliminate this factor.

Occasionally, random, powerful power supplies can enter the power supply system. More often this happens when the wire of trolley buses or trams breaks and comes into contact with the lines that power ordinary houses.

Welding work has a fairly strong effect on voltage, causing flickering and prolonged surges.

The listed reasons are quite enough to think about buying a voltage stabilizer for a house or apartment, and the rating of the best voltage stabilizers for an apartment or summer cottage in 2020 will help you with this. You should especially consider purchasing this product if:

• you live in an old apartment with a small mains voltage limit;
• you live in an old apartment / house where the wiring has not been changed for over 30 years;
• you live in a private home, especially away from emergency services;
• you are a lover of an abundance of household appliances everywhere;
• a large object is being built near your house;
• you live in an area with frequent thunderstorms or in a permafrost zone.

Top voltage regulator manufacturers

This rating lists the pros and cons of devices from different companies. There are firms that offer budget, premium and medium-cost solutions. It all lies in the parameters.

Regardless of the difference in price, each of the brands presented in the top has earned itself a positive reputation in the territory of the Russian Federation and is ranked among the leaders, according to buyers. Consider the top companies.

"Resanta"

The brand manufactures products with an excellent value for money ratio. Their devices contribute to the normal functioning of both small and large household appliances, preventing breakdowns due to interruptions.

For the most part, the company offers customers 1-phase devices. The assortment of the brand includes both relay-type devices and solutions with double energy conversion.

"Energy"

The company dates back to 2000. At that time, she launched the products of other companies on the market, but after a while she changed her qualifications and became a manufacturer of electrical appliances.

Today the brand boasts of its design department and production facilities, which are located in the territory of the Russian Federation and China. In the process of manufacturing products, the company is based on the rule of reasoned value, the safety of using its own products and its high quality.

"Rucelf"

This is almost the key opponent of the Resanta company, which supplies high-quality units, if we talk about the ratio of cost to quality. It is for this reason that the products of this company are in demand on the market. The brand's products differ from the competitors in safety, ease of use, ease of installation and solid appearance.

Rucelf devices are used systematically and constantly. The brand thinks about the safety of its own units from possible overheating, overloads and excessive noise, in connection with which the average life of the devices is 10 years.

"Calm"

This brand supplies both inexpensive solutions, and units of the middle price segment, as well as premium models. Among them, double conversion devices are in high demand, which practically do not lose to UPS.

The company focused on the production of two series:

1. Instab.
2. Instab +.

These lines are manufactured using inverter technology. Due to this, the regulation process is carried out in several stages. At the same time, in the comments of buyers, no complaints were found about the response interval, which, by the way, is minimal here.

"Sven"

The company's products are used in apartments, houses and office premises. The devices of this brand are notable for their affordability and, at the same time, good quality. This is evidenced by the fast switching interval between the windings (the greatest response time is 10 ms), long wires (1.7 m on average), resistance to negative temperatures (-40 degrees Celsius), as well as resistance to high humidity (about 80 -90%).

The range includes wall and floor devices that are protected from impulse noise, overload and overheating. That is why it is not at all surprising that the durability of the products is 10 years.

• View. By design, the devices are divided into relay, electromechanical, mixed and electronic. Each type has its own advantages and disadvantages. It is worth knowing about them so as not to be disappointed in the operation.
• Before you go to the store or order the stabilizer you like online in the online store, it will not be superfluous to calculate the voltage limit values ​​in your 1-phase network. As a rule, there is a drop to 90-140V, but sometimes there is an increase to 270V. Focusing on these parameters, you should choose a stabilizer.
• Load. It is imperative to calculate what load will be applied to the device. For this purpose, it is necessary to sum up the power of household appliances and other equipment of increased sensitivity. Experts advise choosing a stabilizer so that its active power is about 20 percent higher than the value you received. For example, a stabilizer is enough for a PC and TV, the power of which ranges from 500 to 1000 watts.

• Efficiency. The stabilizer consumes electricity, and therefore one of the selection criteria is the efficiency. The larger it is, the more efficiently the device will function and the less energy consumption will be.
• Error. Often, users have electrical appliances that are highly sensitive to the stability of the power grid. In such a situation, experts recommend paying attention to such a criterion as an error (alignment accuracy). This parameter calculates the accuracy / inaccuracy of the voltage output from the instrument. Regulatory documentation, this parameter does not exceed the value of 8%, however, ideally, experts advise you to take a closer look at stabilizers, in which this value is no more than 5 percent.
• Noise level. When connecting the stabilizer to a refrigeration unit or a gas-type boiler, do not forget that the device will operate constantly. The noise level is often the primary criterion, in particular if the stabilizer is located near a child's room or bedroom.

In conclusion, it should be noted that the stabilizer is considered to be a stationary type device, which means that most of the models are distinguished by their large weight and dimensions. All this can cause inconvenience to users, therefore, if it does not come out to hide the unit behind the curtain, then it is better to take a closer look at the models and add design and ergonomics to the list of selection criteria.

If you are still confused by the prices of stabilizers and you are still thinking whether to buy this unit, remember how much household appliances cost in your home. In addition, the gimbal is a device designed to last for decades. And finally, know that in case of a breakdown of appliances at home, it is almost impossible to prove someone's guilt in court. Especially if these are natural disasters like storms or thunderstorms. No service is formally worried about a stable voltage in your home. Therefore, you can only take care of this yourself.
