Modern apartments and houses are oversaturatedelectrical appliances. Their excess causes shortage and surges. In order for all household appliances to survive after the next drop, consumers have to purchase voltage regulators. The market offers a variety of products at different prices and customer needs.
Usually the 380V voltage regulator looks likemetal box, which has terminals for connecting the input and output wires. Also on the front panel can be placed devices for monitoring the voltage and current consumed by the load on the network. On the case there are usually a lot of holes and slots for cooling the internal filling, as it can generate a lot of heat under load.
Inside is an autotransformer and electronicunit, in a pair, they react to changes in the input voltage and instantly change it, which at the output gives a stable, high-quality current to power different equipment.
Many probably remember the Soviet times, whenEach tube TV was connected through a droning heavy box. This was the stabilizer of a small power of 200-250 W, mainly intended for television receivers. It was noteworthy that in the cities it was possible not to use them, but in the villages the 380V voltage regulator was irreplaceable, since the network had 180V and the TV simply did not work. Why did this happen? The fact is that in the villages there were 1-2 substations each, and the length of the lines was very long, due to which there was a voltage drop, and besides, the house was closer to the transformer, the higher the voltage in it, and in the last buildings it was critically small. Then rescued such a necessary voltage regulator 380V 15kW.
Since those times immemorial, nothing has changed.Transformers and lines are basically the same, and equipment and technology has become much more. Repeatedly, it was possible to see or read in the news about the appearance of 400V houses in sockets, which led to massive damage of electrical property and non-return by the services of damage to the injured residents. This was obtained by overloading electrical networks and burning a working zero. And although many devices have built-in stabilizers, they may not provide really high-quality equipment protection.
This is where the 380V industrial voltage regulator specially designed for this function comes to the rescue. For a home or a modern apartment it is necessary.
In a modern store, you can choose a stabilizervoltage 380V and 220V. It is not difficult to guess that for an ordinary apartment or house you need a single-phase 220V. Sometimes there are houses where there are three phases, in this case a 380V voltage regulator is needed. The same applies to small businesses, firms and workshops, where machines are installed with engines in three phases.
In order not to spoil expensive equipment, a voltage stabilizer will also help here.
With the voltage figured out, now on what currentbuy a device? You might think that the more, the better, but you need to take into account the cost of the device: as power grows, so does the price. Therefore, overpaying, you can not use half the potential of the stabilizer, but then spend a lot. Usually 5-10 kW is enough for a house and an apartment. This can be determined by counting all possible included appliances in the house and finding out the total power.
A stabilizer may be suitable for a small business.voltage 380 V. If the consumption is much higher, we select accordingly. Fortunately, they are power up to 80 kW and above. For each there is its own, for different needs.
Special attention should be paid to quality.purchased stabilizer. After all, a huge number of manufacturers, and choose among them is not always easy. I would not want to spend money and get a poor-quality product that at the first voltage surge does not protect the equipment, and even fail. I wanted to draw your attention to the Resanta devices. These stabilizers have a fairly low price, but provide good quality stabilization.
Take, for example, a three-phase stabilizer380V "Resanta", providing the maximum allowable load current of 6 kW and a voltage of 380 V ± 2%. Mechanical switches provide an opportunity 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) provides a low noise level, which is sometimes important when installed indoors. The metal case provides rigidity and protection against mechanical damage. In addition, the stabilizer itself has a fairly modern and aesthetic appearance, and its 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%.
Of course, you can do without a stabilizer, butis 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 greater. And even if there are no big jumps, the 380V voltage regulator will still provide a longer life for your electrical equipment.
