Tips for choosing a voltage stabilizer for an apartment

How to choose correctly

Choosing a voltage stabilizer is not an easy task. It is important to take into account many points so that the device works correctly, performs its functions and does not cause significant damage to the family budget. Consultants in stores will help you choose the best option, but sometimes they try to sell more expensive models or a certain brand, so it is important to have at least minimal knowledge about the device: what they are, how they differ, which one is better. When deciding to purchase, you need to consider the following factors when choosing a stabilizer:

Three-phase or single-phase. The choice according to this criterion depends on the presence in the apartment of devices operating on three phases, or whether the house is connected to a single-phase electrical network. If it is impossible to determine the connection diagram yourself, you should seek advice from an electrician.
Floor or wall (vertical and horizontal). The first option is relatively inexpensive, but has a clear drawback - it takes up a lot of space, and the wires constantly get tangled underfoot. Wall-mounted ones are a little more expensive, but they do not take up much space.

Power. The choice of this criterion is influenced by the number of household appliances in the apartment and their total total power, which everyone can calculate independently. It is also important to take into account the voltage in the electrical panel.
Accuracy - the less error in the operation of the stabilizer, the better, the optimal acceptable threshold is 2%.
Stabilizer type - there are several varieties: mechanical, electronic, compensation, ferroresonant.
Company manufacturer. When choosing a stabilizer (its brand), it is worth reading reviews about the brand, devices; it is better to give preference to European or Russian ones, abandoning Chinese-made devices, although their cost is slightly lower. Popular companies: Luxeon, Defender, Uniel, stationary IEK, Resanta.

The material from which the body is made – preference should be given to metal models, they are more reliable and durable.
Additional characteristics: ventilation, maximum permissible voltage range, control method, is it possible to set the settings yourself, type of coil, is there a capacitor, matrix, microcontroller. It is important to learn about installation methods and what diameter wires are needed.
Price is an important factor, which in some cases becomes decisive.

What is it needed for

A pressing question for many is: what is a regulator and what is it needed for. A mains voltage stabilizer is a device that is connected to the general electrical network and supplies 220V direct current. The need to use the device is due to voltage surges caused by repair work at the substation, frequent line accidents or other factors. Such changes can lead to light bulbs burning out, or short circuits, or damage to equipment that was plugged into the outlet, so it is necessary to provide protection against these problems.

The use of a stabilizer normalizes pressure fluctuations; if necessary, it will decrease or increase so that the output produces the voltage required for consumption. In addition, it will stop supplying current from the panel if the voltage fluctuates outside the adjustable range and an overload condition is observed. What this technique looks like, look at the photo:

Types of voltage stabilizers

The following types of devices are distinguished:

Electromechanical.
Electronic.
Electromagnetic (designed to normalize alternating current), magnetic.
Compensatory.
Ferroresonant.

Electronic

Electronic is a common type of stabilizers. It serves to maintain the output current of a specific strength with maximum precision by regulating a wide range of input voltage. Operating principle: automatic switching of transformer sections using power switches - thyristors, triacs, relays (relay type - you need to open the electric current circuit using a relay). This type has its disadvantages and advantages:

Advantages: silent, equipped with a microprocessor, maximum efficiency, wide input voltage range, long service life, low weight and dimensions, which facilitates installation of the device.
The disadvantages include stepwise voltage regulation, which is limited to an accuracy of 0.9-7%.

Electromechanical

Electromechanical devices for normalizing voltage regulate the flow strength using a special slider, which is controlled by an electric motor that moves current-collecting brushes along the circuit and alternately switches the turns of the secondary winding of the transformer. Pros and cons of such a device:

Advantages: wide range of regulation; output voltage accuracy – 220 Volts; adjustment occurs smoothly; Load disconnection in case of excessive voltage.
Disadvantages: short service life; loud noise during operation; large dimensions and heavy weight, which complicates installation; cannot withstand excessive loads; fire hazardous.

Ferroresonant

Ferroresonance stabilizers are equipment for normalizing voltage, which is used less and less every year. This is due to the outdated operating mechanism (the use of three rods with magnetic flux distribution) and the presence of a large number of shortcomings. The advantages of this type of device include accuracy of regulation and relatively fast response speed. Disadvantages of the device:

Narrow input voltage range.
Large dimensions and weight.
Excessive noise during operation.
May transmit interference.
Withstands minimal loads.

Compensatory

Compensating devices with transistors for normalizing the mains voltage are divided into two types: pulsed (for example, when using arc welding) and continuous; two types - parallel and serial. Such stabilizers have clear advantages: a high percentage of efficiency, accuracy, and stabilization coefficient. Watch the video to learn how the compensation stabilizer works:

Compensation voltage stabilizer

Single-phase

Most apartments use a voltage of 220 volts per phase, so it is recommended to use single-phase stabilizers. This is an automatic device that regulates and maintains constant voltage within the required limits. Errors in operation are 1-7%. The choice is influenced by the load power that the device can withstand and what can be connected to it; it can range from 150 watts to 30 kilowatts.

Three-phase

Three-phase stabilizers are expensive, so if there is a need for such a local device, it is better to use a block of 3 single-phase ones. They can be used in two cases:

The presence of a three-phase consumer in the apartment (such powerful devices may include compressors, pumps, boilers, but they are used in most cases in houses or cottages, and in multi-storey buildings the need to install this type of device rarely arises).
The apartment is connected to the electrical network, a three-phase cycle.

Selection by power

In order to choose a powerful stabilizer (measured in volt-amperes) that would meet the requirements, it is necessary to determine how many devices are simultaneously connected to the network. It is important to understand that not all devices are immediately connected to the network. Add up the power consumed by all devices and add 20% for reserve - the resulting result is the strength that the stabilizer must have in order to perform a reducing, stabilizing function. To determine the maximum permissible power, you need to look at the rating on the input machine.

Selecting a stabilizer based on accuracy and range

Accuracy and range are two interdependent characteristics that influence the choice of device for an apartment. The stabilizer range includes two categories:

Operating - the input voltage is within the limits according to which the output will have the required supply power - 220V.
Limit - at the input voltage deviates from the norm by 14-18%. In this case, the stabilizer turns off all working household appliances in the apartment, while it itself remains turned on, working in autonomous mode to monitor when the indicators stabilize.

Stabilizer accuracy is the maximum point of deviation of the output voltage from the set value; this characteristic is affected by the range of the device. The better this indicator, the higher the cost of the device, which is due to the mechanism of its operation and the complexity of the circuits. Good accuracy is 2%; in inexpensive models, variations from 2 to 7 percent are possible.
