Power supply may be unstable. In many places, the voltage fluctuates in both directions (up and down). These alternating current fluctuations can damage the instruments or render them completely unusable long before the end of the warranty period. When the voltage decreases, the electric current in the device increases, which may cause a fire in the device. Thus, the blocks have found their place in many houses and apartments. This article will talk about their main features, what they do, how much energy they consume and how to choose the best 10kW regulator model.
What are current fluctuations
Voltage fluctuations are changes, increases or decreases in voltage entering the house. In order to reduce such deviations, special devices are needed. 10 kW stabilizers are able to restrain surges in the network. There are models with different operating ranges.
Usually small drops are not dangerous for most devices, but they can damage deviceswith engines. Additionally, they can affect the power of vehicles.
Causes of fluctuations in the house
Voltage fluctuations are usually caused by poor wiring (leading to or inside the house), overloading (using more power than it can handle), sudden turning on of powerful appliances (such as air conditioners, generators), poor power sources or short circuits.
Whenever voltage fluctuations occur, any of these causes must be checked. A 10 kW stabilizer is able to correct such problems. Additionally, the blocks are also used to protect against possible drops in the network.
More about devices
As the name suggests, 10kW regulators equalize the voltage, which means that if the mains fluctuates or changes (beyond or over the allowable range), the device brings the desired range.
This is achieved with electromagnetic regulators that use autotransformer devices. If the output voltage is out of range, the mechanism switches the tap to change the transformer, moving the voltage into an acceptable range. It does not supply direct current to the grid, but operates within a safe range.
How to choose the right model
Determining the right type of voltage regulator for a 10kW home is like choosing a UPS or inverter (backup power). The main thing is to know the load produced on the device. First, buyers need to write down the power(or watts) for all devices that will be connected to the stabilizer. The total amount of power (or watts) consumed will give you the load on the equipment.
But most regulator sizes are listed in VA (volt-amps) or kVA (kilovolt-amps, which equals 1000 volt-amps). Although the user will need to make some measurements to get the actual VA (or Volt-Amp) value in watts (W), for a rough estimate, you can increase the W value by 20% to get the approximate VA size you need. The exact tables with voltage conversions are in the instructions for each device.
Estimates
For example, if the sum of the watts connected to a voltage regulator for a 10 kW home is 1000, you can purchase a device with a little more power. Note that 20% is suitable for residential systems and may not work in industry if there is a poor power factor. High loads require increased performance.
What to look for when buying
Before buying a 220V voltage stabilizer for 10kW, the most important thing to pay attention to is the limit of network operation. The input voltage range is considered a general indicator. This is important because each unit has a minimum and maximum input voltage to which it can stabilize the output network connection.
If the device has an operating range of 150V (min.) - 260V (max.), then when the voltage in the house goes below 150V or more than 260V, the stabilizer will simply turn off the power to this equipment. Butif it is 160V or 250V (within the operating range), the unit will attempt to equalize it to the desired output voltage range.
Overload protection (or surge protection) is another useful feature of the devices. It protects the equipment from a sudden increase in voltage, such as during a lightning strike or short circuit. It is worth making sure that you purchase a unit with such a function so that the devices are safe during sudden power surges.
Are there phase differences
There are differences in power systems. But a 220V three-phase stabilizer for a 10kW house is only required if equalization is needed for a three-phase motor or for network equalization for the entire room. Separate connection is also possible.
All household appliances that are used in the home can be run on a single-phase power equalizer, and a three-phase voltage stabilizer may not be required for domestic use, unless one is trying to equalize the surges of the whole house on this type of connection. This can lead to block failure if the range is calculated incorrectly.
How to connect
It is not recommended to install a 220V voltage stabilizer for a 10 kW home, because these devices also consume electricity, and therefore using them in a common area will consume the network for all 24 hours.
To connect to a specific model, there is a specialconnector. Usually the unit is connected through a system of sockets. All that the user needs to do is to install the plug from the electrical appliance into the desired socket. Mains-powered models are connected at the input. To do this, put a separate pair from the electrical panel on the block.
How much electricity devices consume
Power consumption of voltage regulators depends on the efficiency of the technique. They are usually 95-98% effective. This means that devices consume about 2-5% of the maximum load. Therefore, if there is a 10 kW stabilizer, it consumes about 50 W (at peak load).
If the stabilizer of the declared power is left on for 10 hours, it will consume about 0.5 units of electricity. Thus, leaving it on for 24 hours can result in significant power consumption. That is why experts recommend using a voltage regulator for a single device, and not a unit for the entire line. The main stabilizer must remain on for 24 hours and 365 days, resulting in higher electricity bills.
Are there built-in stabilizers
Today, more and more electrical appliances are using electronic circuits for power management. With systems such as SMPS (switch-mode power supply), voltage management has become much easier.
However, power surges as powerful as lightning can damage your TV. Similarmost refrigerators (especially those with inverter technology) can easily run from 110V to 290V. Appliances such as air conditioners and washing machines need mains units as very few have a high voltage range. Some of them are sold as operating without network equalizers, but it is important to check the input voltage required by the devices and compare it with the common house voltage.
TV Limiters
Most modern LED TVs can operate from 110V to 290V. Low and high voltages do not damage them. LED TVs have a built-in SMPS (switch-mode power supply) that manages internal power.
But they can be damaged by surges, which are sudden increases in electric current. This can happen due to lightning or when the user suddenly starts an appliance that draws a lot of current, such as an air conditioner. To protect the TV from network surges, you need a 5-7 kW unit.
Do I need a device for refrigerators
Most modern refrigerators are designed for a wide voltage range. They can operate between 110V and 290V as they use SMPS technology. It is important to check the wattage specifications of your refrigerator before purchasing a safety box for it. If the operating voltage range is large, then a stabilizer is not required for it.
But if these figures are low, then you definitely need to purchase a block. Most older refrigerators require an additional safety system.
