The occurrences of sag and swell in electric supply is termed as a problem of concern, since it affects the energy quality. To maintain energy quality, it is necessary to eliminate these factors to a great extent. The device used for this purpose is known as DVR which stabilizes the quality of power supply by compensating sag and swells and critical load connected to the industry remains unaffected. DVR is ideal for the application in industries because of its features i.e. low cost, small size, and its rapid response to disruption. In this work, DVR is used to eliminate voltage sag and swell and for one more application i.e. fault compensation by injecting missing voltage from the auxiliary power source.
