Automatic Voltage Regulators (AVRs) are widely used in industrial and household application to obtain the stability and good regulation of different electrical equipment. Hence, we must know the best capabilities an AVR should have.
Surge protection feature cannot be removed from an AVR as it is one of the main purposes of it. When power supply suddenly rise with a great intensity, surge protector built-in the AVR shields the computer or any other connected equipment from that strong power flow. With an AVR, the equipment is safe and secured as it continues to operate.
Short Circuit Protection
Whether it is a circuit breaker or a fuse, what’s important is the protection it gives when short circuit happens. This feature of an AVR will cause the fuse or breaker to blow or trip first before anything can happen to the equipment associated with it. But this doesn’t mean that the AVR is damaged. Circuit breakers as short circuit protectors automatically trip and cut the power off. Fuses on the other hand, blow and also cut the power line. Thus, it must be reset or replaced upon occurrence of the short circuit.
Line Noise Reduction
The audible noise released from high-voltage lines is caused by the discharge of power that happens when the intensity of the electrical flow on the conductor surface is greater than the intensity necessary to start a flow of electric current. AVRs reduce line noises which can irritate users when using light or heavy-duty equipment.
Servo Motor Technology
Servo-Motor AVR uses an advanced electronic controlled servo-motor concept to control a motorized variable transformer. Because of the motors involved, there is a small delay in voltage correction. However, the output voltage is accurate. This capability of an AVR tends to be extremely effective when considering large applications, as it is able to maintain its accuracy despite of input balance and load balance at any power factor.
