TUTORIAL: Application and Control of
Phil M. Camp, Amicon, Inc., Charlotte, NC
In many segments of industry, product is continuously handled in roll form requiring unwinding after the manufacturers process and then rewinding after the process. During these steps it is very easy to damage the material if not executed in a proper manner. Damage can occur due to many reasons that generally relate back to the tension stability and the profile that the material is subjected to by the equipment. The mechanical and electronic factors in the winder design that may need to be considered are addressed by this tutorial.
BMW PLANT TOUR
The newest icon of upstate South carolina, this million plus square foot facility is world class and turning out nearly 300 cars a day. We will visit the Zentrum with the history of BMW and then see the assembly line. Unfortunately, there are no door prizes! This tour is limited top 80 people, so pre-register early!

Updating Old Process Control Systems to
Moving Out of the Stone Age!
Richard A. Fuselier, PE, Hoechst Celanese, Greer, SC
The challenges and pitfalls one faces when upgrading an old process to DCS are examined. Techniques to deal with technical, inter-personal and inter-departmental issues are described based on personal experience.
The Impact of Power Disturbances on
E. Randolph Collins, Jr., Ph.D., PE, Clemson University
A voltage sag for as little as 2 cycles at 50% of nominal voltage can cause an AC contactor to temporarily disengage. The result can be as insignificant as a nuisance trip, or a very expensive process shutdown. This paper discusses how point-in-wave and magnitude affect contactor operation, and why mis-operation seems to be random when compared against disturbance analyzer data. Guidelines which help mitigate contactor operation will be provided.
An Intuitive Analysis of Harmonic-Power
Flow in Electrical Distribution Systems
Roger W. Cox, Cutler-Hammer, Pittsburgh, PA
A procedure is presented for identifying the source of harmonic currents in the power distribution system as measured at various feeders and loads. Examples are given to show why some harmonics exist while others do not. Harmonic cancellation is explained along with a tool for understanding and predicting the results.
The Air Circuit Breaker 50 Years
Stuart Jackson, Instel, Inc., Greenville, SC
If you cannot fully program your VCR, you may be in trouble with your new low voltage breaker. This paper briefly reviews the last 50 years of its development and the complexity of todays features and their applications.
Session Chairman Lou J. Guidotti, Jr., Rockwell Automation
Power Quality: A Utility and Industry
Wayne L. Stebbins, Hoechst Celanese, Rock Hill, SC
Jeff G. Dougherty, Duke Power Co., Charlotte, NC
Current information and case studies on power quality issues as they affect end-use equipment will be presented. This presentation defines power disturbances in industry-accepted terms, reviews the sources and effects of these disturbances (for both the utility and industry), and proposes economical solutions based on the compatibility of the equipment and the environment.
Installation Considerations for IGBT AC
Gary L. Skibinski, Allen Bradley, Mequon, WI
The advantages of Insulated Gate Bipolar Transistor (IGBT) drives over Bipolar Junction Transistor (BJT) drives are considered. They include lower device switching losses and more efficiency; however, some installation issues must be addressed when utilizing IGBT drives. This paper provides a basic understanding of these issues and how to deal with them.
Restructuring the Electric Utility
William H. Fox, Jr., Duke Power Co., Charlotte, NC
Retail competition means that some people like you and I will be able to choose our electricity supplier. This paper presents: a brief overview of the retail competition pilot that is going on in New Hampshire; whats happening nationally; and power companies positions and key issues.
Open Communication Architecture with
Emphasis on Drive to PLC Communications
Erich Sisa, Siemens Electric Limited, Mississauga, Ontario, Canada
This paper deliberates the requirements to successfully monitor and control a production environment. A PLC and drive system for a typical application is used. The communication link using an "open system" is demonstrated. Also the transmission speed required to transfer necessary amounts of data and other advantages will be discussed.

Session Chairman Ronald Ghizzoni, Rockwell Automation, Greenville, SC
Effect of Voltage Sags on AC Motor Drives
E. Randolph Collins, Jr., Ph.D., PE, Clemson University
AC motor drives are often perceived to have better voltage sag tolerance than DC drives due to the uncontrolled rectifier on the front end and the energy storage in the DC bus capacitance. Although this is generally true, manufacturers have devised other methods to enhance drive ride-through capability. These methods are reviewed.
High Resistance Grounding & Fault
Finding on 3 Phase, 3 Wire, Delta Power Systems
Dave Lubich, Milliken & Company, Spartanburg, SC
A debate has existed in the textile industry for years concerning grounding of low voltage power systems. Since reliability and continuity of service are important, many prefer using an ungrounded system. This paper shows that the use of high resistance grounded, low voltage systems should be considered. Design, construction, operation and maintenance factors will be discussed.
Economic Justification of Process
Improvement and Automation Projects
Brian Baldwin, ABB Industrial Systems, Inc., Deluth, GA
Economic justification is the "burden of proof" for the necessity of process improvement and automation projects. This paper describes the steps required to determine the financial return for the prospective project while taking into account life cycle costs.
DeviceNet: A Review of the Open
Communication Networks Standard
What is DeviceNet? An overview of why it was developed, its protocol, and functionality. Who is ODVA, Open DeviceNet Vendor Association? Examples are given of where DeviceNet is being used today.
