Introductions and Opening Remarks
Kevin Bort, TMEIC
The following presentation will welcome attendees to the course and give a brief overview of the following topics for each day. The course is structured to build on the information presented the day before, and groups topics by major operating centers in a typical mill. Power distribution and hot end will be covered throughout day one, while system automation models, gauging and motors will be covered day two, wrapping up with how all the systems tie together in day three. Further discussion on how to become involved with AIST and the Electrical Applications Technology Committee will be included.
