Voltage Stabilizer :-
We all use electronic appliance in our households like TV, Refrigerator, Air Conditioners, Washing Machines etc and to operate these appliance we need an adequate amount of electricity power supply. Usually, in small towns, cities and especially in rural areas there is always heavy power cuts and voltage fluctuations.
As as result, due to low power the electric appliances do not work properly and in long run they get damaged. Also, in big and small industries like manufacturing plants, Hotels, Bars, Colleges, Banks, Government as well as private firms, where power load is always high they need big advanced servo voltage stabilizers to run their devices properly. So, you must install a good voltage stabiliser in your household or office or industry etc as per your energy consumption. A voltage stabiliser not only control voltage but also saves life of your electric equipment/device.
What is Voltage stabilizer?
Voltage stabilizer is also known as Automatic Voltage Regulator (AVR). It is an electronic equipment that stabilizes the AC voltage. It is is designed to control the AC voltage fluctuation up to a certain limit and transfers a stable AC voltage.
Why we need an automatic voltage stabilizer?
As voltage fluctuations is a big issue in India particularly in small towns, cities and rural areas and low voltage can ruin the life of electric appliances so to protect the life of electric equipment and appliances automatic voltage stabilizer are installed. The main function of automatic voltage stabilizer is to safeguard the electric equipment. Also, it saves electric power consumption so energy saving is an another advantage of installing automatic voltage stabilizer.
What is Servo Voltage Stabilizer?
It is automatic but an advanced technology. Servo stabilizers use servo motor for voltage correction. These servo voltage stabilizers are mainly used in big and small organizations, factories, college, companies etc for high output voltage accuracy.
Which is better Automatic Voltage Stabilizer or Servo Voltage Stabilizer?
Well, it depends on your power consumption. If need it in your house then go for automatic voltage stabilizer and if you are running your factory, big store or any company then you must buy a Servo Voltage Stabilizer.
- Which Voltage Stabilizer is good for Home?
- Check Input Voltage range
- Check Output Voltage range
- Note total number of electronic appliances in use
- Check KVA rating of the electric appliances
- Over/Under voltage cutoff
- Type of Control circuit
- Note load type : balanced/unbalanced
- Note voltage type : balance/unbalanced
Types of voltage stabilizers
The can be categorized mainly into three types:
(1). Relay type Voltage Stabilizers
(2) Servo based Voltage Stabilizers
(3) Static Voltage Stabilizers
(1). Relay type Voltage Stabilizers: The Relay type Voltage Stabilizers normally stabilize the input fluctuations of ±15% with an output accuracy between ±5% to ±10%.
(2) Servo based Voltage Stabilizers: Used for very sensitive appliances and equipment and need accurate input power supply (±01%)
Further Servo based Voltage stabilizers can be classified into three categories:
(a). Single Phase Servo based Voltage Stabilizers (220-230 volt)
(b)Three Phase Balanced type Servo based Voltage Stabilizers
(c)Three Phase Unbalanced type Servo based Voltage Stabilizers
(3). Static Voltage Stabilizers: It has Power Electronic Converter Circuit to stabilize the voltage and Voltage stabilization is within ±1%
A filtered, controlled and stable power supply feed is very important for electric devices. A voltage stabilizers makes sure that the devices get desired and controlled voltage irrespective of of voltage fluctuation and protect devices from sudden voltage fluctuations and surge. Also, a good stabilizer safeguard the life of electronic appliances.
