What is a AVR - step voltage regulator?

A step voltage regulator helps prevent a poor-quality signal from being sent over distribution lines to users. Step voltage regulators are mainly used in utility distribution applications for the disbursement of electrical signals to properties. A step voltage regulator provides a means of delivering a much more dependable power signal to users, even in high-demand areas where the incoming signal may become unstable due to the number of consumers drawing off of it.

In many locations, there is an increasing energy demand. This increased demand is due, in part, to heating and air conditioning units becoming more frequently used. The number of users that require a more constant streaming of voltage can create voltage irregularities. This often results in rolling blackouts or more simple undesired effects, such as a TV signal that flickers or lights that dim and brighten on their own.

Voltage regulators aim to deal with this problem. They resemble metal cylinders with coiled antennas coming off of their tops. They also have various capacitor boxes attached to them depending on the needs of the particular voltage regulator.

Such regulators are located most frequently on power line poles or supports, as that is the best way to keep them from being tampered with. Due to the fact that they contain the number of windings they do, voltage regulators are available in two forms. Each of these is a different type of step voltage regulator.

One form of step voltage regulator is the step-up regulator. This acts as voltage amplifiers for areas that don’t have enough power signal without the amplification. The other form is referred to as a step-down voltage regulator. These are used when a terminal or signal to a certain area is too strong, which can cause system irregularities as well as damage electric devices.

Regardless of whether it’s a step-up or a step-down voltage regulator, the main function of a step voltage regulator is to maintain a steady voltage and regulate the amount of voltage delivered to the area around it. These regulators are given a specific range of voltage they are allowed to let pass. No matter how much energy a community needs, the regulators determine the amount of voltage that is consistently driven to an area through power lines and transformer circuits.

These voltage regulators are also a community’s first line of defense for power surges. They generally perform their surge protection duties on much larger scales than that of the in-home voltage regulators. Such in home regulators are most commonly called surge protectors.
