Voltage stabilizer 220V for cottages: which device to choose

Voltage stabilizer 220V for cottages: which device to choose for the protection of equipment

The time spent by amateurs in the country has long gone beyond the summer months. Many people prefer to live in the country from the onset of spring until late autumn, equipping it with the necessary electrical equipment: starting with an iron and a kettle, ending with welding machines and pumps. Given the quality of electricity supplied to the villages of the dacha type, the electrical equipment in the country is at risk of being irretrievably damaged. We suggest you to read the article “220V voltage stabilizer for cottages: which device to choose for the protection of equipment”, the recommendations of which will help in choosing the optimal converter.

Household appliances and appliances may suffer from voltage fluctuations in the power grid of a suburban village

The need to connect a voltage stabilizer 220V for the cottage

Most often, in suburban and suburban settlements, there is a reduced voltage in the network. This is explained by the following circumstances:

• the use of low-power and old transformers that are not designed to service such a large number of houses and a large load;
• remoteness of suburban buildings from the line of analysis of electricity;
• simultaneous use of a large number of power tools and electrical appliances. In such a situation, the main part of household appliances cannot work in the correct mode, and sometimes does not work at all.

Most often in suburban settlements there is a reduced voltage in the power grid

An increase in the voltage in the network of suburban settlements happens less often, however, it can lead to equipment failure or failure of individual blocks and elements.

If you will be at the dacha only occasionally, this will not protect household appliances from a possible sharp voltage drop and, as a result, its failure.

The only correct solution in this case will be the purchase and installation of an acceptable voltage stabilizer for the cottage.

220V voltage stabilizer for cottages: which one to choose (single-phase or three-phase)

Points that should be taken into account when going to purchase a household voltage stabilizer for home and country:

• the power supply system of the house is single—phase or three-phase;
• total capacity of the available electrical equipment;
• how much will the planned stabilizer have resistance to voltage drops, the speed of reaction to fluctuations and the tolerance of overloads;
• the ability of the rectifier to operate in a wide temperature range;
• the cost of the device and its reliability.

Usually in country houses and cottages there are single-phase power systems, but it happens that the owners provide themselves with three-phase power for the use of special electrical equipment. In accordance with the power supply system, voltage stabilizers are also selected: if the cable to the house contains two or three wires, a single-phase equalizer is required, if there are four wires, a three—phase rectifier is required. In the case of a three-phase system, if it is not planned to use three-phase equipment, it is possible to connect three single-phase stabilizers.

Before proceeding to the analysis of various stabilizer models, it is necessary to plan how the rectifier will work: whether it will be used for the entire system or connected to some electrical equipment.

Choosing stabilizer power

To determine the power of the planned stabilizer, it is necessary to find out the required rated power of the circuit breaker on the dashboard. If the machine is designed for 40A, then this indicator should be multiplied by the existing voltage of 220V. As a result, we get 8.8 kW. This figure should be guided when choosing the power of the rectifier. In addition, it is recommended to choose a stabilizer with some power reserve (approximately 20%). So, in our case, you should opt for a voltage stabilizer for giving 10 kW.

Useful advice! The efficiency of the stabilizer depends on the indicator of voltage deviation in the network. A very low voltage will contribute to a lower efficiency of the device. Therefore, it is necessary to choose a stabilizer an order of magnitude greater in power from the estimated power of the devices.

Of course, quite powerful models of rectifiers are characterized by high cost. For the purpose of a more accurate calculation, it is possible to sum up the capacities of all electrical equipment and equipment located in the country. However, do not forget that the starting power of equipment that has electrical equipment in its device will increase 3-5 times. These indicators must be taken into account when determining the capacity of the equipment.

You can also connect through the stabilizer only certain equipment at your discretion, for example, only a refrigerator and an air conditioner. Then it will be quite enough to purchase a voltage equalizer with a power of 3 kW. Such a 220V voltage stabilizer for a cottage will have a much lower price.

Choosing a stabilizer according to the main characteristics

The criteria for choosing voltage equalizers for country houses are based on the fact that most often a country house is used on a case-by-case basis. As a result, the country house is not heated in winter, and the electricity supply in such areas is obviously of poor quality. In this case, such characteristics of the devices as operability at negative temperatures and the possibility of voltage stabilization in a wide range will be important.

Stabilizers for giving must have a sufficient input voltage range, especially for the lower limit. This is necessary so that when the voltage is lowered or powerful equipment is turned on, other appliances in the house do not turn off. In addition, when using household appliances in suburban conditions, a rectifier is needed that can operate in overload and low temperature mode, smoothly adjustable and operating silently. After all, country houses are often equipped with different types of equipment, including high-precision electronically controlled, requiring high-quality protection.

In order to choose the right stabilizer, it is necessary to monitor what the maximum and minimum voltage in the network is. It depends on which conversion range the device will have to be installed with.

Useful advice! For daily measurement of the range of voltage fluctuations in the network, use a voltmeter or fine-measuring pliers.

You should also pay attention to the accuracy of voltage equalization when buying. If you are offered to purchase a device with an adjustment accuracy of 10%, then this indicator is not one of the best and will not always be able to protect high-precision equipment. You should opt for models with an accuracy from 1% to 5%.

The duration of voltage drops also plays an important role. In this case, the stabilizer must have the ability to operate under overload conditions.

If you plan to use the rectifier in winter, you should choose models with the ability to operate at low temperatures.

Features of installation of stabilizers

Thinking about how to choose a 220V voltage stabilizer for cottages and cottages, you should pay attention to the installation methods of the device. Manufacturers offer a floor installation method and a wall mounting option. Considering that country houses, as a rule, do not differ in weighty dimensions, and square meters of area are strictly distributed, it would be ideal to install a wall-mounted voltage converter.

Wall rectifiers have a modern design, do not clutter the room and have a number of qualities to protect electrical equipment in the country.

Wall-mounted voltage converters are installed in the area after the electric meter. All that is required for its installation is to fix the mounting plate on the wall and hang the device itself on it.

Wall-mounted stabilizers are reliable in operation, their use in the country will allow you to be sure of energy saving of household appliances, electric boilers, pumps and power tools. An important feature of wall-mounted analogues is that they can be mounted in unheated utility rooms and function in different temperature conditions, which is especially convenient for country houses and dachas.

Which voltage stabilizers are better for giving: reviews of devices

The main characteristics and cost of the stabilizer depend on the type and device of the device. When choosing, first of all, individual needs should be taken into account. There are three types of rectifiers on the electrical equipment market, the distinctive characteristics of which are given below.

Relay devices. The choice of a stabilizer for the country for many is determined by the cost of the device. From this point of view, a relay voltage rectifier is an actual option. This device has a good equalization speed and a sufficient input voltage range. User reviews indicate a long service life of relay stabilizers, their ability to withstand prolonged overloads (over 100%). The disadvantages include the error of output indicators up to 7%.

The principle of operation of the relay voltage stabilizer

Useful advice! If your house in the country has high-precision equipment that is sensitive to minor voltage fluctuations, you should choose a stabilizer with an alignment accuracy of less than 3%.

Electromechanical stabilizers. Such devices have 2-3 transformers in their composition, have sufficient power and an acceptable price. The advantages of these devices include users: accurate output voltage indicators, smooth regulation, low sensitivity to fluctuations, silent operation. Electromechanical rectifiers tolerate short overloads up to 200%. This type of stabilizers also includes electrodynamic converters capable of operating at low negative temperatures up to -20 ° C and withstanding short-term overload (2 min) up to 200%, but their price is much higher.

The use of a voltage stabilizer for the cottage will ensure stable operation of electrical equipment and equipment

Electromagnetic rectifiers. These devices are perfect for working in cottages located in an area with harsh climatic conditions. They easily cope with their functions at low (up to -40 °C) and high (up to +50 °C) temperatures, endowed with a high rate of stabilization. It is known from the reviews that electromagnetic converters work noisily, so it will be important for them to choose a place outside the living rooms. In addition, they are sensitive to frequency changes and when the load is reduced by 15%, they stop their work. This should be taken into account when choosing devices for suburban settlements, where voltage surges are quite large.

The correct choice of a voltage stabilizer for the cottage is guaranteed to ensure uninterrupted power supply of electrical equipment and extend the service life of existing equipment.
