Overcurrent Coordination for Industrial Applications
Learn about time-current curves (TCCs) and the associated characteristic curves for relays, molded-case breakers, etc. Define the time required between devices to achieve selective operation, how fault current variations affect timing, protection requirements for equipment and cables, and a process for coordinating and overall system.

Doug Durand received his BSEE degree from the University of Texas at Austin in 1986. Mr. Durand started his career in the Systems Planning department of West Texas Utilities before joining Brown & Root (now KBR) in 1987. He has worked in all phases of project execution from conceptual engineering to field commissioning. He is currently the Chief Electrical Engineer and lead of the Electrical Technical Services group for KBR’s Houston office. The group’s primarily tasks involve power system studies including short-circuit, load flow, static and dynamic motor starting, overcurrent coordination, underground cable ampacity, ground mat, arc flash, harmonic load flow, transient stability, and relay configuration/setting. Mr. Durand is a Professional Engineer (Texas), an IEEE member, and was the Assistant Technical Editor of the 1990 revision of the IEEE Brown Book (Std 399).
