Voltage dip immunity of equipment and installations - Status and need for further work

Abstract

This paper presents the results from the work of WG C4.110, a joint working group by CIGRE, CIRED and UIE. Its mandate period stretched from early 2006 through early 2009. The group has addressed several aspects of the immunity of, especially, industrial equipment against voltage dips. Compared to the work earlier groups, the equipment performance is not seen as a final aim, but as a step towards the ultimate aim: allowing the process to ride through the voltage dip. Some of the contributions and conclusions from the WG C4.110 are discussed in this paper, Check Mark Description of voltage dips, Check Mark Equipment and process immunity, Check Mark Testing and characterization, Check Mark Economics, Check Mark Immunity classes and application, Check Mark Further work. © 2010 Chinese Soc for Elec Eng.link_to_subscribed_fulltex
