INDUSTRY NEED
Extruded cable systems, primarily cross-linked polyethylene (XLPE), are increasingly the cable of choice for new underground transmission throughout the world. These systems offer several advantages over older paper-insulated pipe-type and self-contained cables but require special consideration to properly design, successfully install, and ensure long-term operation. This course will focus on these areas to give the student much of the required background needed to apply extruded transmission cables.
COURSE OBJECTIVE AND SUMMARY
This course will present characteristics of extruded cable systems as compared to other cable types, as well as discuss differences between transmission and distribution voltages where extruded cables have seen applications for 30-40 years. The design studies needed for extruded cables will be discussed, along with installation, operation, maintenance and testing.
Expected Learning Objectives / Outcomes
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 extruded cable systems. An engineering degree, preferably in power engineering, is desirable, but not required.
PREREQUISITES
Participants: This course is intended as an introduction for engineers and field personnel involved with planning, designing, or operating an extruded power cable system.
COURSE OUTLINE
INSTRUCTORS FOR THE COURSE MAY INCLUDE
Rachel Mosier, P.E., Principal Engineer, Power Delivery Consultants, Inc. Ms. Mosier has been conducting ampacity analyses for more than 20 years, as a cable engineer working for a large utility as well as for other utilities around the country, often for non-standard installations. She is a member of CIGRE, and an active member of the IEEE PES Insulated Conductors Committee (ICC).
Peter Tirinzoni, P.E., Principal Engineer, Power Delivery Consultants, Inc. Before joining PDC, Mr. Tirinzoni was the cable engineer for a large utility in the northeast, where he was responsible for the design, installation and maintenance of several new cable systems, including the largest 345 kV XLPE cable system in North America. He is a past Chair of AEIC Cable Engineering Committee and EPRI Underground Task Force. He is a member of CIGRE, and an active member of the IEEE PES Insulated Conductors Committee (ICC).
CONTINUING EDUCATION UNITS
Upon request, PDC will issue students a course certificate indicating the number of Continuing Education Units for the course completed based on national guidelines and the number of classroom hours. 2.1 Continuing Education Units (CEUs) will be awarded for successful completion of this course. One CEU is equal to ten classroom hours.
TUITION AND ENROLLMENT
The tuition cost includes enrollment, a comprehensive set of course notes, breakfast, lunch, and coffee breaks, as well as a class dinner on the first night.
