When is a voltage stabilizer needed for household appliances in a home?
Content:
Today, the number of household and multimedia appliances in each family is growing by leaps and bounds, and all appliances consume electricity. The voltage stabilizer for the refrigerator, computer, TV and other devices that make the life of a modern person easier and more interesting will protect complex equipment from changes in the electrical network. The acquisition of such a device is especially important for residents of small cottage villages and detached houses, where the input voltage in the network does not always correspond to the optimal value.
What is a stabilizer and why is it needed
A change in voltage negatively affects all devices that consume electricity. It has been established that differences in the network shorten the life of devices by four times, and energy-saving lamps fail even faster.
Fluctuations are caused by load changes, and they are inevitable. How often electricity “jumps” depends on the length of the power line, the connection of some powerful energy-consuming device, and sometimes the time of day, because the evening load on the network in the village is always more than daylight. As a result, burned household appliances and losses to the owners.
To avoid these troubles will help the voltage stabilizer - a device for automatically maintaining voltage at 220V at its high or low values in the supply network.
This useful device not only increases productivity and extends the life of household appliances, but also saves energy. Modern stabilizers, both in appearance and in functionality, are incomparable with those voluminous rumbling boxes that were installed next to the television set 30–40 years ago. Today it is a small device with a convenient display, on which indicators of the voltage in the network are displayed. The device works absolutely silently. Many devices have a delay function, due to which the start of the TV or refrigerator is delayed for several seconds, during which the regulator will check the signal quality.
Do I need a stabilizer for the computer
In the life of a modern person, computer technology occupies a special place. You can’t do without it at home or at work. Every family certainly has at least one computer, and sometimes several. This electronic device has a complex device and requires special care, and most importantly - high-quality electricity.
A sudden shutdown of the computer threatens serious troubles to its owner, the smallest of which is the loss of unsaved data or typed text. Frequent automatic reboots caused by power surges will quickly bring sensitive equipment out of operation.
A stationary personal computer is equipped with its own power supply, which is able to protect the device from weak changes in the network. But a sharp jump in electricity can destroy the most serious components, right down to the motherboard.
A voltage regulator will help protect your computer from potential danger. Perhaps for residents of large cities, where everything is in order with electricity, this acquisition is not relevant, but in remote areas a computer stabilizer is needed.
For one computer, a 500 W stabilizer is suitable.
LCD TV Stabilizer
All modern televisions manufactured later than 1985 have pulse power supplies operating in a wide voltage range. The manufacturer reports this with the inscription 110-260 V AC (or similar) on the rear panel of the device. The electric current when passing through this node is straightened to the optimal value, so the LCD TV is not threatened by the burnout of transistors or other troubles.
A short circuit will not damage the latest technology, unless it happens on the TV itself. In the event of a short circuit somewhere in the electrical circuit, the TV will simply turn off and the current will be redirected. Another thing, if we are talking about an old tube TV, which is still preserved by some frugal grandmother. Here you just can not do without a stabilizer.
Does the refrigerator need a voltage regulator
The refrigerator can perhaps be considered the most essential unit in the household. It's a shame if, due to unstable voltage in the network, such a necessary thing fails.
It is worth remembering that breakdown of the refrigerator due to power surges does not entitle you to warranty repairs.
A voltage stabilizer is needed for the refrigerator. In connection with the special device of this type of household appliances, the regulator must be single-phase, with a power of at least 220 watts.
Installing a stabilizer will protect the main components of the refrigeration unit, namely the compressor engine and electronic control, from damage during voltage changes in the network to a smaller or larger side.
Of course, in a house located in a metropolis, there is less chance of spoiling the equipment due to power surges and power surges. However, in settlements remote from the center, where the quality of electric routes is not sufficiently monitored, such breakdowns are quite possible.
Stabilizer for gas and electric boiler
Many modern homes are equipped with heating boilers:
- gas
- electric
- invertor.
This equipment creates and maintains heat in the room, and also heats the water. The most complex electronics is responsible for the operation of such devices, because all processes are carried out autonomously, almost without human intervention.
The voltage regulator in the network is necessary for an electric and especially for a gas boiler.
If the electric boiler breaks and suddenly stops working, this is not so bad. In the worst case, the owners will freeze slightly until they put in new heating equipment.
It is much worse if, due to electricity failures, the start sensor in the gas boiler fails or does not work correctly. The device will turn on automatically, despite the fact that the electronic ignition does not work. Natural gas will accumulate in the room, and this poses a direct threat to people's lives.
Sometimes it’s not immediately possible to guess about a breakdown, but only after a while, when paying for utility bills a strong over-consumption of gas or electricity is found. To protect yourself from these troubles and save the family budget, you need to purchase a voltage stabilizer for the boiler.
Stabilizer for a washing machine
Any washing machine requires high-quality and stable electricity. The washing process usually lasts at least one and a half hours. At this time, all the most important electronic nodes operate in extreme mode. If the voltage in the network rises sharply, the electronics and engine of the machine - parts that are particularly sensitive to power surges - will fail.
In addition, even a non-working washing machine can be damaged due to an unstable power supply. Therefore, at the end of the wash, be sure to disconnect the appliance from the network.
For the washing unit, a voltage stabilizer is required. Moreover, the power of the device should be 10% more than the power consumed by household appliances.So, if the LG washing machine has a power of about 2 kW, it is recommended to buy a stabilizer for 2.5 kW or even 3 kW.
Allowable deviations of voltage from the network from normal are indicated by the manufacturer in the data sheet to the washing machine. In the event of unforeseen power surges, expensive equipment may fail or may not work properly.
How to calculate stabilizer parameters
It is not necessary for each household appliance, whether it is a refrigerator, washing machine or computer, to buy a separate stabilizer. It is more convenient and more expedient to use one device for all the equipment available in the apartment. The main thing is to correctly calculate the power of the device so that it is enough to protect several electrical devices. If you buy a stabilizer of obviously low power, it will not be able to fulfill its protective functions, and there will always be problems with the equipment.
To calculate the power of the stabilizer, you must do the following:
- count the number of electrical appliances that are planned to be connected to the regulator;
- for each device, write down the energy consumption declared by the manufacturer from the data sheet;
- add the written values;
- add 20% to the amount received.
Thus, if the total power of all home appliances is 5 kW, then the stabilizer should support at least 6 kW.
In addition, the choice of power of the voltage stabilizer depends on the number of phases in the network of an apartment building or a separate cottage. Information on this can be found in the special inscription on the counter.
For a person who is absolutely not versed in electrics, it is very difficult to correctly calculate the required power of a voltage regulator in a network. In this case, it is better to contact specialists.
Residents of small settlements, where, as practice shows, various violations in the networks are not uncommon, it is recommended to have a voltage regulator. This will protect expensive devices from sudden power surges, extend the life of devices and the quality of their operation. You can purchase and install a common powerful controller on all devices or one for the most expensive and necessary device, such as a boiler or a TV. In large cities and towns, where the voltage in the network is usually within the established limits, you can do without a stabilizer.
