Causes of power surges

Globally, all causes 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 themselves / a group of devices).

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

Of the external factors, the most common is the lack of stable operation at transformer substations. The fact is that many of these substations are morally and physically obsolete. They are badly worn and need to be replaced, but they are not always replaced on time. And over time, the load on them is constantly increasing, 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. Mankind has not yet learned how to transmit electricity through the air, so it is delivered to homes by wires, which usually have very fragile and unreliable protection. Wire breaks, their overlapping, lightning strikes, fire - all this leads to undesirable surges in power consumers - our household appliances.

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

An uncommon but common cause of surges is a weakening in the system ground. If it is broken, 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 cause of jumps is network congestion. Always a network in a house or apartment has its limit. It can be lower (in older houses) or higher (in new ones). But he is always there. And there is always a risk of exceeding it. Especially given the rapid acquisition of new and more powerful household appliances by the population.

It may also happen that some small building or a small residential house was demolished, and a much larger house or office was erected in its place. Comparing the energy consumption of a small home and an office is obvious. However, the network drawn to the object remained the same. Therefore, incidents in the form of overloads are obtained.

The human factor also affects voltage failures.Elementary marriages during the installation of a transformer or poorly laid wiring can give regular power surges.

The household appliances themselves can also be assembled poorly. 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 location factor affects if a new plant is built next to the house or apartment. Or a mall. 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 from time to time.

The notorious lightning strike into power lines gives sad consequences for them and end users. Even lightning protection is not able to completely eliminate this factor.

Accidental high power sources can sometimes enter the power supply system. More often this happens when the wire of trolleybuses or trams breaks and comes into contact with the lines that feed ordinary houses.

Welding work affects the voltage quite a lot, causing flickering and continuous surges.

These reasons are enough to think about buying a voltage stabilizer in a house or apartment. And the rating of the best voltage stabilizers for an apartment or a summer house in 2019 will help you with this. You should especially think about buying this device if:

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

1 Quattro Elementi Stabilia W-Slim 1000

An automatic voltage stabilizer will equalize deviations in the household electrical network to a standard level of 220V and will reliably protect equipment such as ventilation and air conditioning systems, gas boilers, pumping equipment (for a well) in a country house or at home. It will also be useful to connect such expensive household appliances as a refrigerator through it - power surges will not be able to harm sensitive electronics.

In the reviews, the owners pay attention to the compactness of the relay stabilizer

Wall mounts allow you to place it in the most convenient place on the wall, which will save you from hanging wires (they can be placed in a special casing) and cases of careless use (when the gas boiler is in the kitchen, this possibility is most likely). The appearance of the model is also positively evaluated - a compact rectangular case with a digital display will look organic in any room, and the mains cable and load socket located on one side wall of the stabilizer allow you to optimally solve the supply of power cables by hiding them in a special box

The appearance of the model is also positively evaluated - a compact rectangular case with a digital display will look organic in any room, and the mains cable and load socket located on one side wall of the stabilizer allow you to optimally solve the supply of power cables, hiding them in a special box.

4 Storm! PS9315

The most optimal performance makes Sturm! PS9315 is quite a popular stabilizer for installation in a country cottage or in a private house. Its advantage in the form of affordable cost is almost undeniable. However, floor placement and the largest weight (57 kg) in the category makes it impossible for the owner to compactly install the device in the hallway by hanging it on the wall. This stabilizer requires a separate place for itself, and just putting it in a corner will not work - the side walls are perforated for air access, and should not be limited by anything.

In terms of performance, for its price Sturm! PS9315 is quite good. It maintains a stable 220V (+-3%), even when the voltage drops to 140V at the input of the house. This, of course, prolongs the life of a refrigerator, gas boiler and any other expensive equipment. The owners in their reviews indicate a fairly serious protection from external factors. So, the stabilizer can work in rooms with humidity up to 95% and air temperature of at least -5 ° C, which allows you to install the device in an unheated dressing room at home (of course, not in the northern regions of the country).

Top Electronic Models

There are 2 types of electronic equalizers - triac and thyristor. The first option is preferable, since the efficiency of devices is higher, the speed is also higher. The advantage of electronic devices is silent operation. Minus - high price.

The device and principle of operation of the voltage stabilizer

The device of such equipment may vary, depending on its type. But the principle of operation is identical for everyone. The incoming input voltage is smoothed by various nodes, as a result of which even the slightest drops disappear at the output, regardless of the backbone network.

Many modern stabilizers also have their own built-in battery, which allows the equipment connected to it to work for some time when the mains voltage is turned off. Most often, computers are connected to these to be able to save information from RAM.Such equipment is called UBS (uninterruptible network device). But if you need to connect several household appliances to one stabilizer, it makes no sense to purchase equipment with a built-in rechargeable battery. Its cost is quite high, and the charge is unlikely to last for a long time.

But if you simplify everything, similar equipment will look like this

Having understood in general terms how a voltage stabilizer works, it makes sense to understand what parameters you should pay attention to if you decide to purchase a device for your home? Let's try to figure it out

How to choose the right stabilizer

Before you choose a voltage stabilizer for your home, you need to read the opinions of people who have already bought the device and familiarized themselves with its work. Thanks to the reviews, you can compare and analyze the characteristics of each model.

In addition, you yourself need to know what technical indicators are important when choosing. Therefore, in order to be calm for the safety of the house and the equipment in it, the voltage regulator for giving must meet the following requirements:

match the number of phases connected to the house;

A three-phase stabilizer is used if there are more powerful devices in the country

• the output voltage from the stabilizer should be enough for all electrical appliances in the country;
• the operation of the stabilizer must be silent so that the residents do not feel discomfort.

Let's consider each of the points in more detail.

Device phase

Each stabilizer can be single-phase or three-phase. Before buying, you need to find out how many phases are connected to the house. If you yourself took care of the electrification of the dacha, then there will be no problems with determining the phase.If the summer cottage was purchased along with the house, then you can determine the number of phases by the wires going to the meter.

If one phase is connected, then two wires will be stretched to the house. One of which is phase, the second is zero. If a three-phase network is connected, then from 4 to 5 wires will stretch to the house. The easiest way is to determine the number of phases by the counter. It indicates the phase of the network.

A three-phase network in the country is rarely connected, most often it is used to operate a sawmill, sauna, electric boiler. Household appliances used in the country house consist mainly of a refrigerator, a washing machine, lamps, and a microwave oven. For the operation of these devices, a single-phase connection is sufficient.
 

A single-phase network device is needed to protect a single piece of household appliances from voltage surges

Working range

At the second stage, before choosing a 220V voltage stabilizer for the home, you should check the operating voltage in the network. To do this, you need to measure the voltage every two to three hours for a week. The most important thing is to take measurements in the evening, when all the neighbors in the village are connected and at night, when there is practically no current consumed. A voltmeter is used for measurements.

All readings must be recorded in order to subsequently analyze the voltage in the network. Thanks to these figures, you can determine which voltage stabilizer to choose for a private house.

Stabilizer Power

When selecting a device for power, the consumer can perform the following actions:

• buy a device for 10 kW;
• determine the power of the stabilizer based on the corresponding inscription on the machine;
• calculate the power coming from all electrical appliances that are in the house.

Ease of use

When choosing voltage stabilizers for the home, factors such as:

Noise

For comfort in the house, it is important that all electrical appliances work without extraneous sounds. These include electronic and inverter stabilizers.

Electromechanical ones make a buzzing sound, and relay ones make even more noise, so it is important to consider these features of the device when it is planned to install it in a residential area.

This is how the relay stabilizer is arranged

• Brightness of indicators. There are stabilizers equipped with indicators with a bright glow. At night, it brightens up the room. And people who are annoyed by light should not buy such devices.
• Installation method. In order to protect a separate household appliance, the stabilizer is placed directly next to it on the floor. To protect the entire line, the stabilizer is mounted on the wall near the shield.
• Frost resistance. Provided that in winter the stabilizer will also be involved in the work, then you need to choose a model that easily tolerates frost. Such options can be found among electronic and relay options.
• transit mode. For household appliances, sometimes you need to get power, which bypasses the stabilizer.
• Turn-on delay. Household appliances operating on freon, after an emergency stop, need to restore pressure in certain areas of it. Therefore, this function in the stabilizer is important for its normal operation.
• Voltage indication. Many stabilizers are equipped with indicators that show the voltage of the incoming and outgoing current. It can be a digital display or a gauge with an arrow.

The screen of the stabilizer has a bright backlight

Choice by power

If the voltage in the outlet drops beyond the permissible values ​​​​(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 current stabilization only to extend 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 accumulators, batteries, protect microcontrollers.
All devices that are included in the "risk group" are divided into two groups:
Those that have only active power (convert electricity into heat or light, for example, light bulbs, electric stoves)

It is full, it is indicated in the data sheet in watts, it 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.
Those that have active and reactive power (work on the basis of engines or have impulse blocks - vacuum cleaners, computers). Their total power may not be indicated, in order to find out it, you need to divide the active power by 0.7.

If you want to choose a stabilizer for local protection of several devices or installation of a device for the whole house at the electrical panel, the total power of all equipment must be summed up

The result should not be higher than the performance of the device.
In summer 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 figure by 3 times. Add 20-30% to the power to have an extra supply for emergency supply.
