This presentation will focus on power distribution reliability from an overcurrent protective device application as it pertains to selective coordination. The importance of short-circuit calculations and the role of these short-circuit currents will be reviewed in the selection of overcurrent protective devices to selectively coordinate. This presentation will also look at other aspects of reliability and safety including addressing incident energy. The session will also provide a basic understanding of arc flash risk.
Identify the importance of fault current calculations in the selection of overcurrent protective devices to meet design goals of selective coordination.
Develop an understanding of selective coordination as a design goal and methods to achieve more reliable selectively coordinated infrastructure.
Describe best practices for achieving cost-effective selective coordination solutions.
Assess the available tools that can be an asset to the design engineer in selection of overcurrent protective devices.
