High performing automatic voltage regulators should be able to handle loads with high starting currents, all power factors, and high crest factors. Voltage regulation solutions must be compatible with the specified load to ensure its operation and to avoid interfering with the operation of other loads connected to the same power source. Ideally, your automatic voltage regulator would avoid all of this if it had low impedance. Interaction between the load current and source impedance can cause low voltage, harmonic distortion, and voltage unbalance.
The goal of an automatic voltage regulator is to achieve low impedance. Impedance is the resistance of a component to the flow of electrical current, measured in ohms. It also allows the automatic voltage regulator to be more configurable to all buck or boost, giving it maximum voltage correction for extreme cases. This feature allows for more low correction, rather than high correction. The input voltage range should be broad and shifted because line voltages drop more than they increase. The first step in selecting the best automatic voltage regulator is specifying your input voltage range. This requirement eliminates three-phase unbalance problems and minimizes voltage deviations. Regardless of these potential obstacles, voltage regulation must be selectable to an accuracy of ☑%. Several factors can affect voltage regulation, including wire and cable size and type, transformer reactance and cables, motor starter, circuit design, and power factor.
Optimal voltage regulation is achieved when the value of voltage is equivalent to all electrical equipment loads.
