Choosing the right power for an automatic voltage regulator(AVR) requires considering multiple factors, including home electricity demand, voltage level, performance parameters of the voltage stabilizer, and safety and stability.
Here are some key steps and considerations to help you make a wise choice:
→ Understand home electricity demand:
First, you need to understand the home’s electricity demand, including the number of family members, the types and number of home appliances, and daily electricity consumption. The greater the home’s electricity consumption, the greater the power of the voltage stabilizer required; at the same time, the types and number of home appliances will also affect the power selection of the automatic voltage regulator(AVR). For example, high-power appliances such as air conditioners and refrigerators require larger voltage stabilizers to meet their electricity needs.
→ Consider the home voltage level:
You need to understand the voltage level in your area. If the home voltage is low, even if you buy a high-power voltage stabilizer, you may not be able to achieve the desired effect. Generally speaking, when the home voltage is lower than 220V, it is recommended to choose a voltage stabilizer with a power of more than 6KW; when the home voltage is lower than 180V, it is recommended to select a voltage stabilizer with a power of more than 9KW.
→ Please pay attention to the performance parameters of the voltage stabilizer:
When purchasing a voltage stabilizer, you also need to pay attention to its performance parameters, such as output voltage, frequency, total capacity, etc. These parameters directly affect the performance and application range of the voltage stabilizer. The output voltage of a household voltage stabilizer should be kept at around 190V and the frequency at 50Hz; the total capacity should be selected according to the household electricity demand, and it is generally recommended to calculate it at a ratio of 2~3A per kilowatt.
→ Pay attention to the safety and stability of the voltage stabilizer:
When purchasing a automatic voltage regulator for home, you also need to pay attention to its safety and stability. This includes checking the product’s production license, certificate of conformity, and other relevant certificates; and understanding the product’s manufacturer and after-sales service information. In addition, you can also refer to other users’ reviews and reputations to better choose a voltage stabilizer product that suits you.
→ Calculate the total load power:
First, determine the power of all electrical devices that need to be connected to the voltage stabilizer. Check the power label of each device (usually in watts) or use a power meter to measure the power. Considering the additional current margin, it is generally recommended to multiply the total load power by 1.2~1.5 times as the basis for selecting the power of the voltage stabilizer.
→ Consider starting current:
Some electrical equipment may require a high starting current for a short period when starting. If such equipment exists, its starting current should be additionally considered, and a automatic voltage regulator(AVR) that can cope with this starting characteristic should be selected.
→ Memory power requirements:
If there are memory devices that need voltage stabilization in the load, their power requirements should be noted, including the working range and maximum current of the stable voltage.
What is the voltage of the household circuit?
The voltage of the household circuit is 220 volts.
The household circuit is generally composed of two incoming lines, an energy meter, a knife switch, a fuse, electrical appliances, sockets, wires, switches, etc. The incoming line is divided into a live wire and a neutral wire. There is a 220V voltage between the live wire and the neutral wire. They constitute the power supply of the household circuit. They are distinguished by a test pen. The live wire can make the neon tube of the test pen glow, and the neutral wire cannot make the neon tube glow.
In the household circuit, the socket is to power movable electrical appliances. The socket should be connected in parallel to the circuit. It is divided into fixed sockets and movable sockets, which are further divided into two-hole sockets and three-hole sockets. The two holes of the three-pin socket are connected to the live wire and the neutral wire respectively, and the other hole is grounded. In this way, when the three-pin plug is inserted, the metal shell of the appliance is connected to the ground.
The solution for the voltage not being enough for 220V
→ Replace the wires :
If the wires in your home are thin and have high resistance, you can consider replacing them with thicker wires to reduce the line resistance and increase the voltage. Install a voltage stabilizer : The voltage stabilizer can stabilize the excessively high or low voltage within a suitable range to ensure the normal operation of household appliances. If there are many electrical appliances in your home or the voltage fluctuates greatly, you can consider installing a voltage stabilizer.
→ Reduce the use of electrical appliances :
During peak hours of electricity consumption, try to avoid using high-power electrical appliances at the same time to reduce the household electricity load and reduce the possibility of voltage fluctuations.
→ Contact the power supply company :
If the voltage in your home is continuously low, you can contact the local power supply company to understand the power supply situation and seek help. The power supply company may conduct line inspections or adjust the transformer capacity and other measures. Regularly check the lines : Regularly check the power supply lines, and replace aging or damaged lines in time to avoid voltage fluctuations caused by line problems.
Precautions and precautions:
→ Measure the incoming voltage:
First measure the incoming voltage at home. If it is lower than 198V, contact the power supply department for repair.
→ Choose appliances with a wide voltage range:
When purchasing home appliances, you can choose products with a wide voltage range to ensure that they can work normally even when the voltage is unstable.
→ Avoid self-repair:
If you encounter voltage problems, do not repair them yourself. Contact professionals or circuit department staff to come to your home to investigate the cause to avoid more serious failures.
→ Check the voltage stabilizer regularly:
When using the voltage stabilizer, check its working status regularly and replace it in time if there is any abnormality.
The above methods can effectively solve the problem of low household electricity voltage and ensure the normal operation of household appliances.
Summary:
The above is about the factors to consider when choosing a suitable automatic voltage regulator (AVR) power supply, the solution when the voltage is not enough for 220V, and what to pay attention to when using household electricity.
