Full Form of AVR:
Automatic Voltage Regulator
AVR Full Form is Automatic Voltage Regulator. AVR is the core of—what are commonly called—the power stabilizers or power conditioners. A standard power stabilizer makes use of an AVR in combination with one or more power quality capabilities, for example, short circuit protection (or the circuit breaker), surge suppression, phase-to-phase balancing of voltage, harmonic filtering, and line noise reduction. As there exists no certain definition of a power stabilizer or a power conditioner, there are several devices that are marketed as power conditioners and do not contain an AVR. It is thus important a consumer does his analysis of power conditioners meticulously before buying one.
There are several factors that contribute to the requirement of an AVR. However, the most important factor among all is financial. An AVR helps in avoiding the costs associated with downtime and equipment damage caused by poor levels of voltage. Apart from this, the following are some of the contributing factors to the need for an AVR in power stabilizers: utility voltage levels, sensitivity to voltage levels, the cost of problems related to voltage, and voltage drops.
An AVR is capable of taking in a wide range of voltage levels. It automatically gives a voltage output with a range of voltage level that is way narrower. It also performs a step up or step down of voltage by which there is the transformation of the nominal incoming voltage into a distinct output voltage level. AVRs are created for the three-phase or single-phase AC applications.
