Which voltage stabilizer to choose for an apartment and a private house

Modern home is replete with all kinds of appliances and household appliances. All of them mainly operate on the mains, where there are interruptions and power surges. To secure household appliances, you need a special device that maintains the output voltage within certain limits. It is necessary to figure out which voltage stabilizer is best for an apartment, and which one is more suitable for a country house.

Advantages and disadvantages of various types of stabilizers

There are many types of regulators for operation in unstable voltage networks. Each of them has its own characteristics and has unique properties. To choose the right device, you need to understand the principle of operation of each, familiarize yourself with the pros, and study the negative sides.

To power household and industrial appliances, an alternating current network with a voltage of 220/380 volts and a frequency of 50 hertz is used. For household electrical appliances, a mains voltage of 190 to 245 volts is permissible. Depending on the parameters of the equipment available in the apartment, you will need a single-phase or three-phase voltage stabilizer (CH). The full power range by types of stabilizers is distributed as follows:

• electronic single-phase from 2 to 30 kVA, three-phase 10–500 kVA;
• electrodynamic single-phase from 0.3 to 135 kVA, three-phase 5–6000 kVA;
• relay single-phase 1–15 kVA;
• ferroresonant from 0.1-15 kVA, three-phase 5-100 kVA.

Depending on the place of installation of CH, there are floor and wall - vertical and horizontal.

Electronic type stabilizers have no mechanical adjustment. All control is performed by a microprocessor. CH electronic type is also called thyristor or triac. They are characterized by high speed regulation. If a welding machine is working nearby, fluctuations in the electrical network are leveled in 0.02 seconds. Possesses reliable protection, practically does not make noise. The device has a long service life, its compact size makes it easy to mount on the wall.

The device has an installed rated output power. For normal operation, the stock must be calculated, which leads to an increase in cost. Budget models have a minimum number of windings, which affects the quality of step regulation. Decreases accuracy and smoothness of work.

Electromechanical stabilizer, also called servo-driven, is made on an autotransformer. The voltage is carried out in a non-stepwise manner. The motor is controlled by a slider that smoothly moves along the turns of the transformer. This type provides good accuracy of the output voltage; at high numbers, the load is disconnected. Wide range of changes - from 150 to 250 V.

One of the useful properties is work at low temperatures and in conditions of high humidity. High-quality devices, where the collector mechanism is a graphite roller, has a long service life. Also the advantage is the low price.

A counterfeit device is short-lived.The brushes quickly get dirty, wear out, start sparking and require replacement. The devices are large, have a large mass, and are fire hazardous. In addition, the device makes noise during operation.

The relay stabilizer has a power relay through which the autotransformer windings are switched. The stepwise principle of operation is similar to that of electronic devices. The high regulation speed makes it possible to smooth out wide-range input voltage surges. There is an electronic short circuit and overvoltage protection system. The device is compact and lightweight.

Disadvantages - stepped regulation mechanism. Has a low power reserve, average noise level. When changing the steps of adjustment, you can hear how the device switches. Regular incandescent bulbs start flashing. The main disadvantage is the short service life.

Inverter or stepless regulators provide double conversion. Voltage correction is fast and smooth, which does not affect other light sources. The inverter has a wide input range and high output voltage accuracy. They have a high speed regulation and protection against loads. As well as the minimum noise level and a long service life. Among the disadvantages is the lack of a power reserve.

The hybrid stabilizer combines several voltage normalization technologies at once. Most often, there are models in which the principles of operation of relay and electromechanical types are combined. The first type is fast, but imprecise. The second stabilizes precisely, but slowly. Its range of action is from 144 to 256 volts. Relay devices turn on when the voltage figures go beyond the minimum or maximum values.

Ferroresonant type - the principle of operation is the effect of voltage ferroresonance in the capacitor-transformer circuit. Devices were widely used in the 60s and 70s to power tube TVs with transformer units. They were distinguished by their durability, had a low cost. They have a number of disadvantages, including the presence of such a passive part as a linear capacitor. They are used less and less.

Voltage stabilizer or line filter

The voltage in the network is variable in nature, it changes according to a certain law. Plug-in appliances not only use energy but also generate electromagnetic interference. In addition, there are swings and surges in the network. The stabilization block provides a constant voltage parameter.

Power surges are possible due to lightning strikes near power lines. They also happen in industrial zones and can be associated with accidents at the substation, deterioration of electrical networks, connection of a large number of powerful consumers.

The surge protector is a stabilization unit with a toggle switch and a group of outlets. It consists of a varistor filter that suppresses impulse noise. Sensitive devices are protected from high-frequency interference by means of an LC filter.

The device operates according to a single-phase scheme, if the network is three-wire, grounding is mandatory, since impulse noise must go to the ground. The varistor is connected at the input. He takes on impulses and does not let them go further. In addition, it is provided for the shutdown of devices in the event of a short circuit or overcurrent.

The power supply of household appliances and electrical appliances is an important parameter on which the quality of work, reliability and safety depend. Most often, a surge protector is used to connect a stationary computer and its components. Poor power supply affects the performance of radio receivers. The TV or radio will interfere. Other devices are also fed through the surge protector.A modern "smart" refrigerator is controlled by a microprocessor and it definitely needs such a device.

The filter can have a different number of sockets, which allows you to connect several different mechanisms at once. The device is designed for a certain load level, exceeding is unacceptable. Therefore, it is impossible to connect several units of powerful equipment at the same time.

To find the right look, you should pay attention to the following nuances.

1. Determine the total peak power of the devices that will be connected. For example, the operation of only one laser printer will require up to 3 kW. For a stock, you need to add 20-25% to the amount received.
2. By connecting additional devices or upgrading the entire system, the power may increase.
3. It is necessary to decide which additional functions will be required and which will be superfluous. A model with telephone wall jack protection is not required if the computer is connected via a fiber optic cable.
4. When choosing, it is better to focus on the reviews of buyers of reputable sites than to study the review of the store pages.

High-quality power supplies are already equipped with filters. They are mounted on the board, especially for high power devices. Unfortunately, the power supplies for the charger, laptop, fluorescent and LED lamps made in China are made without filters, according to a simplified scheme.

When choosing a filter, you should pay attention to the price. It is, to some extent, an indicator of quality. There are many low-end products on the market that do not have a filter circuit. Such a product is not a stabilizer, but can only protect against dangerous voltage surges and serves as a simple extension cord.
