The Tutorial Subcommittee of the PCIC is sponsoring six half-day tutorials Thursday, September 25, 2008. Continuing education units, (0.4 CEU) will be awarded to each participant who successfully completes a course and submits the required CEU form. Light refreshments will be provided during the sessions. A lunch will be provided between the morning and afternoon sessions, (12:00 Noon to 1:00 pm) for all tutorial registrants. The price of lunch is included in the price of the tutorial, so plan to end your morning session or begin your afternoon session by having lunch with your fellow attendees.

The cost of one tutorial will be waived for any first-time PCIC conference attendee. (NOTE: Those who do not pre-register will be charged full price at the door. This policy has been implemented to ensure there are enough hand out materials for all participants.)

Tutorial A (8am - Noon)

Fundamentals of Electric System Design
This course is a two-part course, offered 4 hours in the morning and 4 hours in the afternoon.  For the complete course, sign up for both Tutorial A and Tutorial D.

This course is intended to be the first of a series of courses.  The purpose is to provide post graduate training and education for engineers new to the electric power field.  This first course provides a review of undergraduate electrical circuit theory, and applies those fundamentals to the concepts of electric power.  The course culminates in an example design project starting with a facility layout and producing a single-line diagram suitable for specification.

Tutorial B (8am - Noon)

Guidance in the Selection and Installation of Zone Approved Devices and Equipment

Abstract: This course will cover the selection of components and wiring methods for Zone rated hazardous (classified) locations.  Particular attention will be given to the details that must be considered to ensure proper installation.  Compliance with NEC® requirements will be considered and clearly advocated through the presentation.  Methods for selection to reduce material cost and labor cost will be emphasized.

Tutorial C (8am - Noon)

Grounding and Ground Fault Protection of Medium Voltage Industrial Generators

Abstract: Major and significant changes are occurring in the recommended practices for grounding of medium voltage industrial generators. This tutorial is intended to make those who own and operate industrial medium voltage generators aware of these changes and the fact that currently accepted practice will result in unacceptable generator damage for stator ground faults.  The grounding changes discussed in the tutorial are being driven by in-service events where generators protected according to established practice (as outline in IAS standards) have suffered catastrophic generator ground fault damage. These events resulted in an extensive investigation by a Working Group of the IAS resulting in major recommendations in generator grounding to reduce damage and repair time. These recommendations are now being implemented into ANSI/IEEE C37.101 and C37.102 standards. The tutorial discusses the results of the Working Group investigation. Specifically it addresses: typical generator grounding practices and ground fault protection methods, damage mechanism during stator ground faults, user examples of stator ground fault damage, a new grounding method called hybrid grounding, installation experience with hybrid grounding, impact of grounding changes on system protection.

Tutorial D (1pm - 5pm)

2nd Part of Tutorial A
This course is a two-part course, offered 4 hours in the morning and 4 hours in the afternoon. For the complete course sign-up for both Tutorial A and Tutorial D.

Proposed Author - Fred Bockhurst, PE (Brockhurst Engineering)

Tutorial E (1pm - 5pm)

Application Guidelines: Current Transformer (CT) and Potential Transformers (PT) - Metering and Protection

Abstract: This half-day short course has been designed for all power system design engineers in utilities, petroleum, chemical and process industries and engineering consultants, students in electric power concentration, managers and plant technical personnel and others interested in the subject.  It is assumed that participants have some rudimentary basic and broad knowledge of electric power systems design and protection engineering.  Practical experience is preferable, but not required.  One of the main objectives of this course is to focus on the design, selection and applications of CT’s and PT’s as applied to power systems protection and metering at all voltage (distribution and transmission) levels. Extensive handouts will be provided in the class.  Numerical examples will be discussed to enhance the understandings.

Proposed Authors - Dr. P.K. Sen, PE (Colorado Schools of Mines) and John Nelson, Fellow IEEE, PE (NEI Electric Power Engineering)

Tutorial F (1pm - 5pm)

Improving Reliability for Generators and High-Voltage Motors

Abstract: This half-day course presents many different methods to improving and increasing the reliability on each of your generators and high-voltage motors. The course starts off with a brief description of how these machines work, followed by a description of all the major components. The course then enters into the main portion, which conveys typical generator and high-voltage motor failures that reduce reliability and availability. Common problems such as winding turn shorts, rotor forging cracking are among only a few that are discussed. The size of the machine and the associated failure modes most related to the PCIC personnel will be addressed. Along with each possible failure that can reduce reliability and availability, will also be presented methods for identifying, detecting and eliminating the failure possibility. These will involve all possible test methods, inspection techniques, or component replacement and modifications to correct the issue. An understanding of these generator and high-voltage motor issues will help plant personnel avoid costly forced outages.  The most current industry problems and failure modes are presented, along with many recent case histories. Time is allotted for course attendees to discuss their own case studies and establish next step options for failure prevention. Each participant receives a comprehensive set of course notes. Major topics of discussion include:

• Overview of generator/high-voltage motor and exciter design, operation and component description
• Diagnosis and prevention of generator and high-voltage motor rotor problems, including rotor winding shorts, grounds, copper distortion, balance problems, rotor thermal sensitivity, forging evaluation, retaining ring stress corrosion cracking, J-strap fatigue, rotor dovetail cracking, with many case studies
• Description of rotor testing including megger testing (insulation resistance), pole drop, hi-potential, flux probe, stationary and running impedance
• Diagnosis and prevention of generator and high-voltage motor stator problems, including stator winding grounds, turn to turn shorts, partial discharge, end winding vibration, stator core iron shorting and melting, core looseness
• Description of stator testing including EL CID, core loop & thermography, insulation resistance, winding resistance, power factor, high frequency surge test, current analysis etc. with many case studies
• Participant case studies
