TUTORIAL-1999 Changes in the National Electrical Code – 4.0PDH

1999 brings lots of changes to the National Electrical Code. Not only are there the "normal" changes that occur every three years with the Code, but there’s a new format and look. Come see and hear how these changes will affect you.

Instructor: Marion R. "Pete" Rhea received his Bachelor of Science degree from Clemson University before joining Duke Power in 1951. During his career at Duke, Pete held several positions including Planning Engineer, Planning Supervisor, District Engineer, and Supervisor of Distribution Services. He also served as Codes and Standards Specialist and retired from Duke after 42 years of service. Pete remains involved in the NEC and is a Certified Instructor by the State Board of Examiners of Electrical Contractors, and by the NC Code Official Qualification Board.

8:55 am Testing Electrical Power Systems for Safety & Reliability

J. B., Franklin- Hood, Patterson & Dewar

Methods of testing electrical power systems are discussed. Recommendations are given concerning types of tests to be performed on equipment and systems and how to determine what tests should be performed. Guidelines for acceptable values are also given and discussed.

9:35 am A Simplified Approach to Reliable High Quality Critical Grade Power

This paper discusses a simplified UPS technology called diesel no-break. The nature of the system, extended power outage protection and continuous active voltage regulation and filtering, result in high quality power afforded to the customer.

10:15 am COFFEE - COKE BREAK

10:25 am Parallel Active Harmonic Filters: The Electronic Solution for Harmonics and Power Factor Correction

Parallel active harmonic filters are just emerging as a viable technology. This paper discusses 1) what a parallel active harmonic filter is; 2) a comparison of current product design/application emphases; 3) application comparisons to passive harmonic filters; and 4) performance of an active filter.

11:05 am Power Quality In The Polymer Processing Industry

Jeff Dougherty, Duke Power

The purpose of this paper is to provide an update of the power quality initiative aimed at the plastics and polymer processing industry. With the goal of identifying unique power quality problems and solutions, EPRI and Duke Power embarked on this initiative in late 1997. The initiative involves equipment testing for five customer types: blown thin film, plastic jacket, thick film, injection molding, and plastic pipe. CommScope, Incorporated of Hickory, NC became interested in the initiative at its inception and has since then partnered with EPRI, Duke Power and the Polymers Extension Program to test their extrusion equipment, implement solutions, and has offered their case study to promote this power quality initiative.

1:00 pm Selection of Power Cables for PWM AC Adjustable Speed Drives

David Mercier

This paper identifies and discusses the reliability issues associated with three-phase electric motors controlled by constantly improving, fast-switching pulse-width modulated ac adjustable-speed drives and the selection of the power supply cable.

2:00 pm Soft Start Vs AC Drives - Understand the Differences

Walt Lukistch

This paper will review the basic operating principles of soft starters and variable frequency AC drives. A further analysis of these technologies, reviews how motor performance is affected. These affects are compared in order to provide insight into proper selection of either soft starters or AC drives.

2:40 pm Analysis of Mechanical and Electrical Noise Interfacing the Instrument during Data Acquisition: Development of a Machine for Assessing Surface Properties of Fiber

Yuksekkaya & Oxenham

A new compression test unit was developed for the assessment of the surface properties of fibers. In order to measure the variation in the compression force during a test, a full bridge load cell was developed. It was seen that the signal coming from the strain gages was superimposed with noise. It was also found that the noise was from both electrical and mechanical sources. An extensive mathematical analysis of mechanical noise and the application of a mechanical noise reduction technique minimized the mechanical noise component.

3:20 pm COFFEE - COKE BREAK

3:35 pm NEW PRODUCT PRESENTATION - To Be Announced

3:45 pm ONLINE MEASUREMENT OF FABRIC MECHANICAL PROPERTIES: COMPRESSIONAL BEHAVIOR

Huang & Ghosh

The principle of the on-line measurement of compressional behavior being developed is based on the analysis of fabric deformation while it is passed through a nip formed by a pair of rollers, one of which is controlled by a motor and is attached to a load cell. The specimen to be tested is moved continuously through the measurement system, while it is compressed with constant speed in the nip area. Thus load-displacement relation of the fabric is then obtained as a function of time and the fabric stress-strain relation in compression is obtained.

4:25 pm NEW PRODUCT PRESENTATION. To Be Announced

ENTERTAINMENT – The Young Singers of Callanwolde

The Atlanta Young Singers is a group of 150 children, grades 3 through 9, who are involved in a choral training program. During the 24-year history of the Young Singers, the lives of many hundreds of boys and girls have been enriched through a child-centered training program focused upon musicianship and quality performance.

The group has performed for the President of the US, at the Washington National Cathedral, with the Atlanta Symphony and at Family Christmas Concerts conducted by Robert Shaw, in addition to all major capitols of Europe. The Atlanta Young Singers performed, and recorded, the feature song "Power of the Dream" for the closing ceremonies of the 1996 Olympics. Their resume includes having been winners in the International Choral Contest at the Hague, and the Johnny Mann Choral Festival in Atlanta.

8:30 am A Novel Approach To Machine Fault Diagnosis And Prognosis

Vachtsevanos

This paper addresses issues relating to diagnosis and prognosis of machine failures. These functions are essential in an intelligent control paradigm where fault-tolerant control algorithms are employed to assure survivability of critical systems. The enabling technologies involve a fuzzy logic based expert system that diagnoses impending failure modes when low-bandwidth process data are available and a new MIMO wavelet neural network for high-bandwidth measurements. Results from a typical testbed will be used to illustrate the effectiveness of the approach.

James Toth, General Electric

This paper will review several types of power monitoring equipment available today to perform power quality studies. It will include some of the "classical" single function recorders to the more modern multi-function analyzers. It will also discuss the capabilities of each instrument, the sensitivity of the settings, the type of data recorded, how this data can be used, and how to interpret the data recorded.

10:15 am Advances In Flywheel Energy Storage Systems

Joe Schatz, Southern Co.

This paper presents the technology of using a flywheel battery, a unit that combines the most attractive features of modern and classic flywheel designs to deliver 800 kW of power while occupying less than 10 square feet of floor space.

10:55 am Application of Kalman filtering on a scanning measurement platform

Chuck Wells, VP Engineering, Impact Systems

This paper presents a new approach to computing estimates of the cross directional profile and its covariance matrix based on measurements from a mechanical scanning sensor traversing a moving web. State estimators are normally formulated with a static measurement matrix; however, in the web scanning application, a dynamic measurement matrix is used.
