This paper describes the impact of voltage sags on the utility and industrial customers. Several utility measures are presented to minimize the customer`s exposure to voltage sags. However, these measures cannot completely eliminate the impact of voltage sags on sensitive equipment. A case study is presented in this paper that includes measurement results that were used to characterize the voltage sags experienced on the utility system and in the industrial facility, simulation results that were used to develop area of vulnerability curves for the industrial facility, mitigation equipment that was employed to improve the sensitive equipment`s ride through capability, and the lessons learned from the systems approach analysis.
