INDUSTRY
NEED
Pipe-type cable systems may be buried, but they are not dead! They have a long, reliable history and continued to be installed today even as XLPE cables gain popularity. The unique as-pects of pipe-type cable systems require special considerations, and many utilities have lost the senior level experience necessary to design, op-erate and maintain these systems. This 3-day course co-sponsored by Public Service Electric & Gas Co., focuses on the design, ampacity, speci-fications, installation, uprating, maintenance practices, dielectric fluid-handling systems, and life evaluations of both high-pressure gas-filled (HPGF) cables and high-pressure fluid-filled (HPFF) cables.
COURSE
OBJECTIVE AND SUMMARY
The course will explain the unique aspects of pipe-type cables as compared to other cable types and then discuss various topics regarding the reliable operation of these systems including cathodic protection systems, pumping plant requirements, dissolved gas analysis (DGA), cable ampacity, uprating methods using fluid circulation and forced-cooling, and several other topics relevant to pipe cables.
PDC has identified learning objectives we expect each student to obtain on completion of this course. The student completing this course should be able to:
WHO
SHOULD ATTEND
The course will be valuable to engineers responsible for planning, operating or designing pipe-type cable circuits.
PREREQUISITES
An
engineering degree, preferably in power engineering, is desirable.

Charleston is a delightful southern city on the water, and is a well-known tourist destination with many historical sites and a great many excellent restaurants. It has been named the best-mannered city in the U.S. for ten years in a row. Check the Convention and Visitors Bureau site at http://www.charlestoncvb.com/
We have obtained rooms at a special rate of $109 per night at a nearby Hampton Inn, West Ashley (Citadel), 678 Citadel Haven Drive, Charleston SC 29414, Tele 843 573-1200. Mention Confirmation No. 8800 0124, Jay Williams.
SCE&Gs Leeds Avenue Training Center is only 15 minutes from the Charleston airport. Contact Jerry Ruschkofski, 803 217-8564 if you have questions about local arrangements.
Jay
Williams worked at Con Edison from
1965 until 1973, and was in charge of Con Eds transmission cable group.
He was manager of the Power Technologies, Inc. Underground Cable Systems
unit when he left in 1992 to found Power Delivery Consultants, Inc. with another
cable specialist, John Cooper. As
Principal Engineer at PDC, he has been responsible for many transmission cable
projects, both pipe-type and extruded-dielectric.
He had developed and taught many courses on transmission cable systems,
and has written more than 50 articles and book sections on the subject.
Bob
Wilkinson has almost 50 years
experience in pipe-type cable systems. He
was a field engineer at Phelps Dodge in the 1950s, responsible for many
pipe-type cable systems. He co-founded UTEC Constructors in 1970, and left UTEC in
1975 to work for Sargent Electric, and then the Westinghouse Electric
Corporation. He retired from
Westinghouse in 1990, and has served as an independent consultant since then,
primarily providing field observer services for underground transmission cables.
He is a PDC associate consultant.
