Protective Device Coordination with EasyPower - Part 2

In Part 2 of this 2-part series on device coordination, Jim Chastain at EasyPower continues his explanation that device coordination can be a complex topic because the process can exacerbate the task of mitigating arc flash incident energy. He explains how to determine if mis-coordination exists and the process to set coordinated protective devices. He then shows how to create a ‘difference calculation’ to graphically show device coordination as well as implement trip settings for fixed time devices. He finishes with an answer to the question, “If this computer is so smart, why can’t it do device coordination for me?”
