Many businesses routinely condition and filter incoming water and even air for their facilities, ... more Many businesses routinely condition and filter incoming water and even air for their facilities, and set up filters for computer and e-mail systems as well. Why not consider the same treatment for electrical equipment? Service reliability and quality of power have become growing concerns for many industrial facilities, especially with the increasing sensitivity of electronic equipment and automated controls. Although utilities do their best to supply reliable, high-quality power, periodic sags and surges on utility lines will continue to be a fact of life. If even a brief shutdown of your process equipment can result in large additional production costs (such as from downtime or scrap product), you should consider protecting your electronic equipment from the effects of power surges, sags, and other disturbances. In this brief we focus on the problem of voltage sags. Electronic devices function properly as long as the voltage (or driving force) of the electricity feeding the device stays within a consistent range. There are several types of voltage fluctuations that can cause problems, including surges and spikes, sags, harmonic distortions, and momentary disruptions. Voltage sag is not a complete interruption of power. Voltage sags pose a serious power quality issue for the electric power industry. Much work has been done assessing the effects of voltage sags on power system operation, and on industrial and commercial loads. However, more research has been needed on the effects of voltage sags on residential loads, particularly sensitive equipment such as computers.
