Voltage sags are momentary dips in voltage that may cause misoperations to the utility customers` sensitive loads. These misoperations may only be an annoyance to the residential sector, but, on the industrial and commercial front, they can cost millions of dollars each year. This cost can and probably will negatively affect electric utilities in the evolving competitive market as utility customers look for alternate suppliers of electric power. Voltage sags are usually caused by remote power system faults associated with equipment failures or temporary faults caused by lightning, animals, or other acts of nature. It is impossible to eliminate all of these faults and associated voltage sags, but an improvement can be achieved through system modifications on both the utility system and the industrial or commercial power system. The evaluation of these system modifications was difficult in the past, but a voltage sag analysis program developed by Power Technologies, Inc. (PTI) has simplified the task. The program uses methodologies developed for the update of the IEEE Gold Book (IEEE Standard 493, Recommended Practice for the Design of Reliable Industrial and Commercial Power Systems). The results of this sag analysis program form the basis of possible future cost-benefit analysis enabling utilities and utility customers to make the most economic system modification.
