Overcurrent Relay Advances for Modern Electricity Networks

Arturo Conde is Professor of Electrical Engineering at Autonomous University of Nuevo Leon, Mexico. He is interested in the protection and power quality of power systems, particularly as relates to relay design, applications of adaptive protection in transmission and distribution systems, and on-line applications through distributed management systems of smart grids. He is the author or coauthor of 33 indexed articles and has authored over 50 papers in national and international congress. He is the author of one book, two patents and three book chapters.
