What is a Stabilizer or Automatic Voltage Regulator (AVR)?
A Stabilizer or Automatic Voltage Regulator (AVR) is a device that maintains a constant and stable voltage level, protecting against electrical issues such as voltage drops or surges. A stabilizer adjusts the current voltage to the appropriate level and smoothens the power supply, allowing connected devices to operate at full efficiency. Consistent current flow not only ensures efficient operation of the equipment but also reduces the rate of damage caused by electrical problems, thereby extending the lifespan of the devices. It is suitable for equipment that needs to operate continuously, such as servers, telephone exchange systems, medical equipment, scientific instruments, industrial machinery, and can be used with many other types of devices as needed.
Choosing an Automatic Voltage Regulator Size
For example:
Example Calculation:
To find the suitable voltage regulator size for an air conditioner of 9000btu, a fan of 60W, a rice cooker of 1240W, and 10 light bulbs of 28W:
Therefore, the safe size of the voltage regulator for the mentioned electrical devices would be 4000W or above, or an 8Kva 6400W voltage regulator.
Voltage Drop Definition: The term "voltage drop" is commonly used to refer to a decrease in electrical voltage, or what we understand as "220 volts". In reality, 1-phase electricity is specified as 230V by the electrical authority, which allows a normal voltage drop of not more than 5% or 220V.
