Modern apartments and houses are oversaturated with electrical appliances. Their excess causes deficiency and power surges. In order for all household appliances to survive the next drop, consumers have to purchase voltage stabilizers. The market offers a variety of products at different prices and customer needs.
Appearance
Usually, a 380V voltage stabilizer looks like a metal box, on which there are terminals for connecting input and output wires. Also on the front panel can be placed devices for monitoring the voltage and current consumed by the load in the network. There are usually many holes and slots on the case for cooling the internal stuffing, as it can generate a lot of heat under load.
Inside there is an autotransformer and an electronic unit, in a pair they react to changes in the input voltage and instantly change it, which gives a stable, high-quality current at the output to power various equipment.
What do you need
Many probably remember the Soviet times, when every tube TV was connected through a buzzing heavy box. This andthere was a small power stabilizer at 200-250 watts, mainly intended for television receivers. It was noteworthy that in cities it was possible not to use them, but in the villages a 380V voltage stabilizer was indispensable, since there was 180V in the network, and the TV simply did not work. Why did this happen? The fact is that in the villages there were 1-2 substations, and the length of the lines is very long, in connection with which there was a voltage drop, and moreover, the closer the house was to the transformer, the higher the voltage in it, and in the last buildings it was critically small. Then such a necessary voltage stabilizer 380V 15kW rescued.
Voltage stabilizers now
Nothing has changed since time immemorial. Transformers and lines basically remained the same, and there was much more equipment and technology. It was repeatedly possible to see or read in the news about the appearance of 400V in the sockets of houses, which led to massive damage to electrical property and failure to return the damage to the affected residents by the services. This was obtained from overloading electrical networks and burning the working zero. And although many devices have built-in stabilizers, they may not provide really high-quality equipment protection.
This is where the industrial voltage stabilizer 380V, specially designed for this function, comes to the rescue. It is necessary for a house or a modern apartment.
Which one to choose
Bin a modern store, you can choose a voltage stabilizer of 380V and 220V. It is easy to guess that for an ordinary apartment or house you need a single-phase 220V. Sometimes there are houses where three phases are connected, in this case a voltage stabilizer of 380V is needed. The same applies to small enterprises, firms and workshops where machines with three-phase motors are installed.
In order not to ruin expensive equipment, a voltage stabilizer will also help here.
We figured out the voltage, now what current to buy the device for? You might think that the more the better, but you need to take into account the cost of the device: with an increase in power, the price also increases significantly. Therefore, having overpaid, you may not use half the potential of the stabilizer, but you will spend a lot of money. Usually, 5-10 kW is enough for a house and an apartment. This can be determined by counting all possible appliances in the house and knowing the total power.
For a small business, a 380 V voltage stabilizer may be suitable. If the consumption is much higher, we select accordingly. Fortunately, they come in power up to 80 kW and above. There is something for everyone, for different needs.
Special attention should be paid to the quality of the purchased stabilizer. After all, there are a huge number of manufacturers, and choosing among them is not always easy. I would not want to spend money and get a low-quality product that, at the first power surge, will not protect the equipment, and even fail. I would like to draw your attention to the devices of the Resanta company. These stabilizers have a fairly low price, but provide goodstabilization quality.
Take, for example, a three-phase voltage regulator 380V "Resanta", which provides a maximum allowable load current of 6 kW and a voltage of 380 V ± 2%. Mechanical pointer devices make it possible to control the voltage at the input and output of the device, as well as the current consumption of the load. There is protection against overload and short circuit at the output. Also, natural cooling (without a fan) ensures a low noise level, which is sometimes important when installing indoors. The metal case provides rigidity of a design and protection against mechanical damages. In addition, the stabilizer itself has a fairly modern and aesthetic appearance, and a weight of 29 kg makes it possible to carry the device without much difficulty. The efficiency of the stabilizer is also indicated by the declared efficiency - 97%.
Conclusion
Of course, you can do without a stabilizer, but is it worth the risk? Having calculated the cost of a TV, a refrigerator, a computer and other, for example, business equipment, you will understand that, in which case, the costs will be much higher. And even if there are no big surges, the 380V voltage regulator will still provide a longer life for your electrical equipment.
