Automatic Voltage Controllers

Automatic voltage controllers (AVC) are the equipment that provide stabilized voltage input to electrical or electronic devices. Also used with transformers , automatic voltage controllers are installed on the incoming side and supply uniform voltage to the distribution transformer. Installation of these devices can be done for both indoor or outdoor applications which protect several electrical and electronic components from sudden voltage fluctuations.

Specification of AVC
Automatic voltage controllers usually consist of:

• It balances the incoming voltage
• Automatic voltage regulator

Features
Some salient features of AVC are :

• A distribution transformer
• Regulate the voltage fluctuations
• It has a independent phase control
• Both oil-cooled and air-cooled models available
• There is a optional digital display and high voltage, low voltage, overload, single phasing, surge & spike protection
• Wide range in single or 3 phase from 2000 – 3000kva
• Distortion less and continuous servo voltage control within +/- 1% accuracy

Benefits of AVC
AVC's benefits include

• Lesser chances of failure of electronic circuit
• Improvement in Power Factor
• Reduction in Breakdown up to 80%
• Energy Saving up to 10%
• Reduction in MDI

Technological Advantages
Automatic voltage controllers sound technical whose technological vantages are :

• Heavy Duty : They are suitable for heavy duty in construction as well as for Industrial Applications
• Efficiency : It is above 90% as compared to other stabilizers available in market
• Life : Life of AVC is around more than 15 years .
• Price Structure : AVC is very cost effective and that price is paid back with in a few months in terms of better efficiency, better life and 100% continuous loading benefits of it.

Application of AVC
AVC finds wide application in almost all types of industries, especially in process plants where an uninterrupted and stable voltage supply is desirable. Some of the areas where AVC finds application are:

• Paper mills
• Textile mills
• Steel Plants
• Food processing industries
• Rubber industries
• Furnaces
• Tea gardens
• IT industries
• Call centers
• Hotels
• High rise buildings
• Multiplexes
• Hospitals
• Research centers
• Nuclear power projects
