The Operation, Application and Comparison of Automatic Voltages Regulators in AC Power Applications


3 The Need for Automatic Voltage Regulation

Many factors contribute to the need for automatic voltage regulation. However, the ultimate reason for using voltage regulation is financial – to avoid the costs associated with equipment damage and downtime caused by poor voltage levels.

This section discusses why voltage levels fluctuate, what can be expected, what type of problems may be encountered and more...
