How to choose a voltage regulator for a private house?

Anyone has ever experienced problems with jumps in the electrical network, but they do not cause any problems to someone, but other people because of this, expensive equipment is out of order. Often, and living in the country is accompanied by such unpleasant moments as jumps in tension, and they seriously spoil life. Neither the crystal clear air, nor the enchanting beauty of nature will help here. And this can become a global problem, because modern equipment and household appliances are excessively demanding for stable voltage and immediately refuse to work if something goes wrong. No help from the state in this situation should not wait - it is better to solve the problem yourself by buying a special device. Therefore, in this article, we'll talk about how to choose a voltage regulator for a private house or apartment on your own.

The principle of operation of stabilizers and their varieties

This information will undoubtedly be useful to you in taking the first step towards solving the problem with permanent power outages. There are three types of similar devices, and in order to understand how to choose the voltage regulator for your case, you need to briefly consider all the varieties.

Relay stabilizers

The principle of operation of such a device can be understood even by a student who taught physics and is familiar with the transformer. Relay stabilizers produce the voltage of the desired value due to the change in the number of turns of the secondary winding. Depending on where the voltage in the coil oscillates, the primary transformer relay changes the number of turns in the second coil. Due to this, we get an adequate and stable voltage output. These devices have more pluses than minuses.

Advantages:

• Affordable price.
• Service life is not less than 10 years.
• Steadily tolerate any overload.
• No noise during operation.
• Work with the lowest and highest voltage.
• The instruments are compact in size.

Important! Disadvantages:

• Not too fine adjustment accuracy, about 8%.
• Voltage changes in stages that can be observed on an incandescent lamp.

Servo Drives

They work in the same way as relay ones, but instead of relays they are equipped with a special electric motor with a servo drive.

Pros:

• Affordable price.
• Highest degree of accuracy of voltage regulation.

Disadvantages:

• Slow reaction to the jumps in the network, the delay is about 1-2 seconds.
• Short service life due to the presence of moving parts.
• Too noisy.

Important! It is better not to use them in houses with large inductive voltages, where there is a lot of large equipment, since the delay in a few seconds may seem like a trifle, but for sensitive technology this is a huge danger. Such stabilizers place in homes with a small number of household appliances.

Electronic stabilizers

This type of device is the most modern, as it was created taking into account the requirements and requests of new equipment. For controlling the voltage drops, triacs or electronic thyristors are responsible here, and not obsolete servo motors or relays.

They react instantly to the change in voltage, which means that the household appliances are under maximum protection. Moreover, the more the stabilizer will have adjustment levels, the more accurate and qualitative it will be to maintain the required voltage level.

Important! They work very long and absolutely quiet. They are expensive, but their price is fully justified.

How to choose a voltage regulator for a private house?

There is a large list of recommendations regarding how to choose a voltage regulator for a dacha or a private house, but the main thing is to learn how to correctly read the instructions that are attached to the device. You need to pay attention to such moments:

• Power.
• Number of phases.
• How long does it take for the device to react to voltage surges.
• The maximum and minimum voltage limits, which must be carefully monitored, because when they reach the device does not work.
• The recommended installation option is floor or wall mounted.
• Output voltage, indicated with accuracy of adjustment.

Special attention should be paid to the power selection of the selected device. It is not difficult to do this if you follow the instructions:

1. Studying its active power, which is specified in the instruction, one should also remember the reactive power that occurs when there is an inductance due to devices with the most powerful electric motors. If this point is not taken into account, the stabilizer will not be able to overcome the maximum load of the network at the start of the device.
2. Coefficient of transformation. When the network issues a voltage of 220V, the device freely passes it through itself and transmits it to all electrical appliances without processing. At this moment, this coefficient is zero. But if the voltage coming from the network is deflected to a greater or lesser side, then the stabilizer aligns it to 220V, while the power is lost.

Important! If you plan to protect only one device from the drops, you can purchase a stabilizer exclusively for it. If there are a lot of sensitive and expensive devices in the house, it will be more rational to buy a 220V stabilizer for the house, which will be able to fully service the entire living area. Due to this you will not experience any inconvenience in using your technique.

Rules for choosing a voltage regulator for an apartment

In principle, it is not difficult to answer the question of how to choose a voltage regulator for an apartment, as we have already found out certain points earlier. Buying this device for installation in an apartment, consider the following factors:

1. Single-phase or three-phase. Determined by this criterion is easy, you just need to consider to which network your home is connected and whether there are devices in the apartment that work from three phases.
2. Wall or floor. The first option will cost more, but such stabilizers occupy quite a bit of space. But floor stands are inexpensive, but here the inconvenience is delivered by wires constantly confused underfoot.
3. Power. As in the case of a private house, it is necessary to take into account the number of appliances and appliances in the apartment, their total capacity. It is also important to take into account the voltage in the electrical panel.
4. Accuracy. Remember, the less errors there are in the operation of the device, the better the acceptable threshold.
5. Stabilizer type. There are several of their varieties: electronic, ferro-resonance, mechanical and compensatory.
6. The material from which the body is made. It is better to prefer the model metal, because it is stronger and more reliable.
7. Cost. This is an important factor, in many cases decisive.

That's all you need to know to choose a voltage regulator for a private house. Once again, review all the recommendations, and then go to the store for choosing the device that suits you. And install it yourself or with the help of a master - decide when the stabilizer will be already in your hands.
