Abstract

CAICEDO, Joaquín; NAVARRO, Felipe; RIVAS, Edwin  and  SANTAMARIA, Francisco. The state of the art and new developments in voltage sag immunity. Ing. Investig. [online]. 2011, vol.31, suppl.2, pp. 81-87. ISSN 0120-5609.

This paper presents the state of the art regarding electrical equipment's immunity to voltage sags. It deals with immunity analysis and voltage sag generators. An alternative methodology for testing equipment regarding voltage sag is proposed, along with immunity assessment. A comprehensive bibliographic review was made, describing voltage sag immunity standards and selected research and industry publications. The proposed methodology for assessing immunity was based on the literature presented and the authors' work.

Keywords : electromagnetic compatibility; equipment immunity; power quality; sag generator; voltage sags.
