Summary:This paper demonstrates practical considerations when studying Overcurrent Protection Coordination in industrial systems and applying related IEEE Standards. The paper is divided into two parts. Part one focuses on protection coordination for High Voltage and Medium Voltage Industrial Systems. Part two covers balance of distribution system topics. The main discussed subjects are time/chronologic, current/amperometric as well as zone selective interlocking coordination. Other factors that affect coordination are also addressed. Suitable selections of the relay time-current characteristic are presented. The paper also includes practical details for accepted Coordination Time Interval (CTI) in coordinated systems.
