This paper discusses the sensitivity of adjustable speed drives (ASDs) to voltage sags and short interruptions on the basis of extensive test results. Existing standards and previously published work are, critically reviewed, and a description of test procedures needed for appropriate assessment of ASD sensitivity is presented. The following tests were performed: sensitivity to rectangular three-phase, two-phase, and single-phase voltage sags with ideal and nonideal supply characteristics, as well as sensitivity to nonrectangular-balanced three-phase voltage sags similar to those caused by the starting of large motors. The results show that although the behavior of this equipment has a rather complex pattern, a simple representation of ASD sensitivity to various types of voltage sags and short interruption can be established.
