Why do we need AVR?
An Automatic Voltage Regulator is an electronic device or circuit that maintains an output voltage to be consistent to its load current. This is necessary because the voltage delivered to your home and mine may sometimes fluctuate which can cause serious damages to your appliance; if not completely destroying it. Fluctuations in power are brought about by so many factors. Some of these may be poor power regulations, electrical surges due to lightning, and many others. An AVR however, has a servomechanism inside that hunts the accurate voltage when surges happen in order to maintain the needed voltage level that ultimately protects your appliance.
Now you may ask, why not use an AVR in all my appliances? This friend may be a logical question but an impractical one. An AVR is usually necessary for appliances and equipments with electronic devices inside that may be sensitive to electrical surges. Examples of which are flat screen TV’s, audio/video equipments, computer systems, modern refrigerators and similar items. Simple home appliances that do not contain sensitive electronic devices like electric fans, blowers, portable radios, etc. do not need AVR’s.
