Fifty years ago, dachas were used only as a place of temporary residence, storage of household items of gardeners, therefore they did not require a large power supply of the country house. Modern country houses – a place of seasonal relaxation, a full-fledged dwelling filled with a variety of household appliances. Old electric lines are increasingly unable to cope with the growing load. As a result, summer residents have a question on the agenda, how to choose a voltage stabilizer for a summer residence, because this device is able to save all summer equipment from voltage surges.

What is a voltage stabilizer for?

All electrical appliances are created for a certain voltage level of the power supply network – 220V, with a normal deviation of 5% in the direction of decrease or increase. An oscillation within 10% (198-242 V) is also acceptable, but it is already critical if the discrepancy becomes large, the devices either turn off (if the voltage drops), or they may burn out (if a surge occurs).

Stabilizers are devices that level voltage deviations. They take current in the form in which it passes through the mains, accumulate, add the missing according to standards or select the extra voltage and supply it to the devices. Passing electricity to the devices through himself, he continues to supply electricity for some time when it is not in the network, equalizing surges and voltage drops, eliminating interference and normalizing the frequency of the home electrical network.

How to choose a voltage regulator for giving

In order to qualitatively secure the operation of all devices, it is necessary to choose the correct voltage regulator. In this case, two basic principles must be guided: the device must operate efficiently and have sufficient power to cover all necessary equipment in case of congestion and other malfunctions in the supply of electricity from substations. Therefore, when choosing a device for country cottages, you must:

1. Calculate voltage drop range.
2. Choose power and accuracy.
3. Select the type of device (speed, noise indicators, number of phases).

Power selection

• With the help of a voltmeter, collector pincers and other power tools, daily measurements are taken to establish the range of voltage in the mains. This will help in choosing a device for power.

• If the voltage in the outlet falls outside the acceptable range (up to 160V), then units with electric motors and high energy consumption (washing machine, refrigerator) may not work. Office equipment with switching power supplies itself stabilizes the flow, therefore it needs to stabilize the current only to extend the work for a while (to turn off the computer so that the matrix with the microprocessor does not burn out). These devices are also used to charge batteries, batteries, and protect microcontrollers..
• All devices that are included in the “risk group” are divided into two groups:
  1. Those that have only active power (convert electricity into heat or light, for example, bulbs, electric stoves). It is complete, indicated in the data sheet in watts, will have the same value in volt-amperes – this is important, since the power of devices for stabilizing the current is measured not in kilowatts, but in kVA.
  2. Those that have active and reactive power (operate on the basis of engines or have impulse units – vacuum cleaners, computers). Their total power may not be indicated, in order to know it, it is necessary to divide the active by 0.7.
• If you want to choose a stabilizer for local protection of several devices or to install the device on the whole house at the electrical panel, the total power of all equipment must be summarized. The result should not be higher than the performance of the device.
• At the cottages there is always a lot of equipment with reactive power (pumps for heating, water supply, compressors). Since they have a large starting power, it is worth choosing a device that exceeds this indicator by 3 times. To have extra power for emergency supplies, add 20-30% to the power.

Choice of accuracy and range

During the initial daily voltage measurements, an approximate range of deviation from standard values ​​should be set. It affects the operation of various devices in different ways, so it is worth choosing a stabilizer that will take into account the thoroughness, or accuracy, of stabilization to satisfy their nutritional needs:

• highly sensitive devices show a malfunction with a slight difference (for example, the lights start to flash, the microwave turns off) – they require stabilization accuracy of 3% or less.
• average household appliances have enough stabilization accuracy of 5-7%

Tips from professionals

• Pay attention to power calculation, this will warn you from unnecessary expenses and ensure the effective operation of the device, as the more powerful it is, the more expensive.
• If you plan to install the device in the house, it is better not to choose relay and mechanical ones, because they make a lot of noise.
• Choose those models that will be repairable in the event of a breakdown and are provided with a professional installation service, tuning with the on-site installation of electricians.
• It’s worth choosing the device taking into account that the nameplate power will become noticeably less if the input indicator is lower than 220V, with significant deviations it can be reduced by almost half.

Types

Stabilizers are divided into several groups depending on the phase:

1. Single phase stabilizers.
2. Three phase.

Types of devices depending on the principle of the mechanism:

1. Relay. They have high regulation speed, high efficiency (Efficiency), low stabilization accuracy, limited output power, do not positively affect the distorted sinusoid. Inexpensive. These include such popular devices Voltron RSN-10000, Power ASN-10000, Energy ASN-5000, UPower ASN-8000, Ryder RDR RD10000, Ryder RDR RD8000 (relay electronic stabilizer automatic).
2. Electromechanical (servo-driven). They have high stabilization accuracy at low speed regulation, response, reliability. No arc distortion. high efficiency, low price. These include, for example, Energy START 10000, voltage stabilizer Luxeon LDS 500 SERVO.
3. Triac. They work through the keys-triacs, which should be closed or opened. Silent, have low accuracy of stabilization, but quickly respond to changes in the network, able to withstand overloads. Reliable, efficiency slightly lower than the previous types. The price is high. These include LVT ASN-350C, Volter SNPTO 9 (y).
4. Ferroresonant. Pros: reliable, high-precision, with excellent speed, withstand significant pressure. Go paired with capacitors. Cons: a small range of regulation, do not work during reboots and idling, have an average efficiency. They have a large diameter and weight, metal. Rare and relatively expensive. These include voltage regulator Eltis TERRA-10000, Elim-Ukraine SNAF-1000.
5. Converters online and with PWM (pulse width modulation). Convert alternating current to direct, autonomous. They accept a wide voltage range at the input, produce a high-quality sinusoid at the output, high-precision, have high efficiency, ventilation, cooling system, protection against short circuit in conductors. Expensive. Volter 7, 9, 11.14 ptm.
6. Magnetic, electromagnetic, step, transistors, with control and others.

One hundred step voltage adjustment

These include relay, triac models. They regulate the voltage according to the coil principle, switching cycles between sections of transformer windings, which have a different number of turns on the rod. Because of this, a change in indicators occurs gradually, in jerks. Modern models have better performance, shorter switching intervals, but do not provide exceptional accuracy and smoothness. Choosing these will be more economical against the background of the validity of these parameters for the correct operation of the devices.

Stepless voltage regulation

These include electromechanical stabilizers, as well as devices of new generations – online converters, models with pulse-width modulation. These are double conversion systems that convert alternating current to direct, with subsequent modeling of its indicators: output voltage, amplitudes, frequencies, or devices operating according to the example of a rheostat. They have high stabilization accuracy, if you choose such equipment, the problem of flashing lights in the country disappears.

Reliability

Reliability of the stabilizer is its endurance in operation, the service life without repair and in general. Different devices demonstrate their level, and this depends not only on the manufacturer, but also on the types of devices themselves, their number. So, it is more reliable to choose several stabilizers to protect one group of devices in the country than one. Relay models are considered more durable than servo-drives, and triacs (see the photo below for an example) than relay ones. The degree of reliability of units with step regulation is also higher.

Rating devices for giving

What type of stabilizer in terms of power, phase, accuracy and method of operation to choose for a summer residence is a matter of affordability and purpose, however, it is quite possible to make a rating of such devices by their reliability and other indicators among manufacturers. Choosing a stabilizer, you can take this indicator into account. Based on the statistics on breakdowns over 6 years, a rating of devices according to the degree of reliability (based on the quality of work and the material used), which can affect the choice of the device:

1. Voltaire.
2. RETA.
3. Phantom.
4. Ortea.
5. Luxeon.
6. Leader.
7. Upower.
8. Donstab.
9. Forte.
10. VoTo.
11. Stabvolt.
12. Rucelaf.
