TUTORIAL: Short Circuit Studies
Jim Toth, GE Industrial Control Systems
This tutorial will review sources of short circuit currents, estimating short circuit current contributions, system impedance elements (e.g., cables and transformers), simplified short circuit calculations, equipment interrupting ratings, and specifying or evaluating equipment ratings based on short circuit calculations. Attendees should bring a calculator with them.

The Energy Policy Act and Its Effect on
Ziba Kellum, IEL
The Energy Policy and Conservation Act (EPACT) is a package of energy conservation measures drafted in 1992 and signed into law in October of 1997. This paper will describe the requirements of the law, which motors are affected, and how the law will be enforced. Further discussion will be provided on motors sold as components of imported manufacturing equipment.
Uninterruptible Power Supply Systems:
Non-Linear Electrical Load Compatibility
Milind Bhanoo, Cyberex, LLC
This paper describes the latest advances in the design of single-phase UPS systems incorporating dynamic digital feedback control to accommodate non-linear loads.
Introduction to Biotemp Fluid
T. V. Oommen, ABB Power T&D
A new biodegradable insulating fluid has been developed from vegetable oil sources for use in electrical apparatus such as transformers. Paper, pressboard and various synthetic polymeric materials are currently used for insulation.
Short Circuit Studies and Coordination
Studies (What, Why & Where)
Bruce Graves, World Wide Technologies
This paper offers definitions for short circuit studies and device coordination studies. The purpose of these studies is discussed.
Session Chairman Ronald Ghizzoni, Rockwell Automation, Greenville, SC
Application of Digital Static Transfer
Switches in Critical Industrial Environments
Milind Bhanoo, Cyberex, LLC
The Static Transfer Switch (STS) selects, at high speeds, between two or more sources of power and provides the best available power. Advances in the sensing of power anomalies and in control of SCRs to enhance reliability will be discussed.
Benefits and Pitfalls When Using
Permanent Magnet AC Motors in Spinning Applications
Robert L. Brown, E. I. du Pont
The advantages of PM motors versus their synchronous reluctance counterparts, however, can quickly be negated by not thoroughly understanding the predictability of the PM motor's performance. This paper offers some insights into predicting performance of PM motors so they can be most advantageously applied in new installations.
NEMA E Design - Motors and Controls
Robert H. Daugherty, Reliance Electric
Jeffrey Kilburn, Rockwell
Issues to be covered include: The characteristics of NEMA Design E motors, the impact of the 1997 Federal Mandate on energy efficient motors, UL and NEC ramifications on control and protection equipment for use with NEMA Design E motors and the potential for nuisance tripping of overload relays and instantaneous circuit breakers when used on Design E motors.
Vision System For On-Loom Fabric
Hamed Sari-Sarraf and James S. Goddard, Oak Ridge National Laboratory
This paper describes a vision-based fabric inspection system that accomplishes on-loom inspection of the fabric under construction with 100% coverage. The inspection system, which offers a scaleable, open architecture, can be manufactured at relatively low cost using off-the-shelf components.

Selecting AC Motor Protection for Plant
and Process Optimization
Walter Lukitsch, Allen-Bradley
This paper will review causes of motor failure and the various types of motor protection available. By proper analysis of the requirements of the plant, the process and the motor, motor protection can be selected which provides the proper protection while minimizing costs and optimizing the process and plant operation.
Low Impact Motor Control With Star-Delta
Phillip W. Rowland, Soigne Associates Inc.
This paper discusses the use of star-delta starters with derivations of starting current and its ramifications.
Distribution of Control Via Automation
Networks Using The Producer/Consumer Model
Joe Kallal, Rockwell
The most important factor affecting these capabilities in the control environment is the network model. The source/designation model used for the past two decades can no longer meet today's network needs. The only model available today that can meet these demanding requirements and allows for future migration is the producer/consumer network model.
High Resistance Grounding for Ungrounded
Chuck Richardson, Duke Power Co.
This paper will discuss the two types of systems, the problem of arcing ground faults, and a solution - high resistance grounding. Test results from four case studies at industrial customer plants and data from a three-wire electrical system test board will be offered.
