In cottages or in country houses, there are often problems with voltage drops in the network. In this case there is a unique solution - the voltage regulator for the house.
Classification of stabilizers. Which voltage regulator is better?
High or low voltage can cause a failure of most electrical appliances. The voltage jumps occur due to the centralized regional setting of the average voltage across the entire length of the power line.
Voltage 220V can be at the midpoint of the line. Depending on how far from this point is the house or cottage, some voltage fluctuations are possible. Accordingly, at home, located closer to the substation will have, more often than not, increased voltage in the network. Houses that are away from the substation suffer from a voltage drop.
To protect the house and electrical equipment from voltage surges, there are special devices - voltage stabilizers for cottages.
The essence of the stabilizer is to control the input voltage. It switches the turns of the transformer, equalizes the current and provides the corrected voltage to the output.
The most common types of stabilizers:
- Electronic or thyristor.
Servo Driving Stabilizer
These stabilizers change a certain number of turns of the transformer, thereby regulating the output voltage. The slider of the servo motor, moving along the turns of the transformer, regulates the input voltage mechanically. Devices of this type do not have reliability in operation.
- Advantages: low price;
- Disadvantages: a lot of mechanical nodes that often fail;
- The most common failure: deviations in the operation of the servo-drive mechanism, sticking of the corner-graphite unit.
Relay Voltage Regulator
It has a switching mechanism that switches the windings of the transformer and consists of a block of several power relays.
- Advantages: it takes the average price place in the market of stabilizers and has fewer mechanical components;
- Disadvantages: limited service life (from, up to 2 years, depending on the frequency of power surges in the network);
- Common fault: sticking of relay contacts.
Electronic (thyristor) voltage regulators
The main mechanism of electronic stabilizers are electronic circuits, seven-strings, thyristor keys, capacitors. These are the most reliable types of stabilizers. They have a long period of operation and will be the best option when choosing a voltage regulator for the home.
- Advantages: speed (reaction of input voltage operation up to 20 ms.), Silent operation (an important component in residential space), an uninterrupted period of operation over a long period, does not require maintenance, convenient interface.
- Disadvantages: cost (approximately twice as expensive as a relay regulator, and also almost three times more expensive for a servo drive).
Which voltage regulator is better?
The best for dacha or home will be an electronic stabilizer. It can be connected right after the meter to ensure the safety of electrical appliances throughout the house.
How to choose a voltage regulator for home
To select the appropriate voltage stabilizer model for the house or house, you need to determine the number of phases of the supply voltage input.
With three-phase input voltage, respectively, requires a three-phase stabilizer. Some owners install three single-phase stabilizers and connect them together.
Most suburban entrances have one phase. For such networks, a single-phase stabilizer is required. Electronic (thyristor or seven-core) stabilizer, is the best and most reliable type of single-phase voltage correctors.
One of the important indicators when choosing a stabilizer is its power, since some models have a negative property of power loss when the voltage in the network drops.
The well-known manufacturers of thyristor stabilizers Lider PS (NPP Inteps Company), as well as seven- electronic stabilizers Volter SMPTO (Company ChNPP Elektromir) have a wide range available products.
Stabilizers have advantageous characteristics of power and performance. All company models have excellent climatic performance (frost resistance and moisture resistance in range -40 C + 40 C), as well as impregnation with special compounds of all the nodes and internal filler plates. Such properties prevent the occurrence of a short circuit when condensate forms inside the stabilizer.
If the stabilizer does not have a similar moisture-frost-resistant treatment, it is not recommended to operate it at minus temperatures.
Stabilizers Lider PS
Created to stabilize the voltage, in the case of fluctuations in the AC network, power and protect a variety of household electrical appliances. Power devices have a range from 100 VA to 30 thousand. VA (single-phase network) and, - 90 kVA (three-phase network). Designed for round-the-clock functional protection of the home network from voltage drops in the range of 125-275V (model W-30), 110-320V (model W-50).
The simplest are the stabilizers Lider PS series W. Their electronic stuffing provides accuracy of stabilization (the error can not be more than,%), and the speed of response of control signals is 250 V / sec. The stabilizer is controlled by an electronic microprocessor (controller).
Stabilizers Volter SMPTO
Designed to adjust the voltage in internal networks, where deviations from nominal voltages are about 5%. The manufacturer offers a large selection of products that have different accuracy of stabilization, - 10%, as well as correction of the lowest input voltage from 85V. The stuffing and stabilizer systems are managed by an intelligent system, whose operation is regulated by the central processor.
According to a review of voltage regulators for the home, Volt SMMPO and Lider PS are the best option. These are quiet, compact and reliable assistants in solving problems with voltage surges in country or home networks.
