Light bulbs are blinking in your house, and the refrigerator is buzzing from time to time? Most likely, it is associated with a change in the voltage in the network. In the evening and morning there is an overload of the electrical strife, which is why the voltage falls. All household appliances are very sensitive and with constant jumps of network parameters may fail. To prevent breakdowns, you need to purchase a voltage stabilizer.

To choose this device you need to know:
power;
number of phases;
voltage operating range;
the number of connected devices.
To find out the power you need, fold the amount of W, indicated in the passport to each domestic instrument. That is, you need to fold the power of the iron, computer, hair dryer and other devices that you want to connect to the stabilizer.

The number of phases in the network will prompt the electrician. Based on this data, it is necessary to purchase a single-phase or three-phase apparatus. What happens in the stabilizer? When electricity flow inside the device, all voltage jumps are aligned. Due to this, electronic chips and basic fees are not subjected to additional load. The whole technique works in normal mode.

To determine the operating voltage range, you can use the use of the electrician, or independently define it. To do this, use the Migometer. This machine is inserted into the socket, while the sensor arrow deflects the resistance value. Above the scale of resistance there are notes with voltage. Measurements need to be produced in the evening when all household appliances are included in the house at the same time. Usually enough stabilizer operating within 165-250 V. If you have noticed that the voltage falls below 165 V, then purchase a stabilizer with an extended working range.

If you want to protect only the computer, you can purchase a small portable stabilizer running from the outlet. But if you wish to protect the whole house, you can purchase a stationary trunk apparatus. It connects to the rubble with a terminal box. Thus, absolutely the whole technique will be protected from voltage jumps.

Do not acquire Chinese devices. Of course, the cost of such stabilizers is low, but the operating power does not always correspond to the stated. It is worth noticeing to the instruments of domestic production. Now companies are engaged in the production of stabilizers:
Calm;
Resanta;
Elite.

The cost of domestic devices is slightly higher, but this is due to the other principle of the work of stabilizers. In the domestic market, quite some stabilizers of European manufacturers. Basically, the entire range is represented by Russian, Ukrainian and Chinese instruments. There are also models of the German company HUTER, the cost of which is significantly higher than Russian. The manufacturer swallows for the quality of the equipment, so the warranty service life is 5 years.
If you disassemble the devices of Russian and Chinese production, then you can see a number of differences. All relays thyristors in the Chinese stabilizer have no designation. Accordingly, they are collected in the same China. Russian manufacturers use both domestic parts and basic nodes of Germanic or Japanese production. This prolongs the service life and reliability of the device.
