The Oregon Graduate Institute of Science & Technology offers 
a short course
Non-Ceramic Insulators: Applications, Design, Testing and Analysis
in Portland, Oregon
July 28-30, 1995

About Non-ceramic Insulators
Electrical insulators are required to fulfill long-term structural roles
in power transmission and substation applications.  In recent years,
composite (non-ceramic) insulators have gradually replaced the traditional
porcelain counterparts in high voltage transmission lines and
substations.  These insulators rely on a glass reinforced polymer (GRP)
composite rod as the principle load bearing component.  In comparison with
porcelain, composite insulators have demonstrated significant advantages,
such as a high mechanical strength-to-weight ratio, improved damage
tolerance, flexibility, impact resistance, and ease of installation. 
However, since these insulators are relatively new products, their
structural integrity and expected life is a subject of great interest to
both utilities and manufacturers.

About the Short Course
A critical and in-depth overview of the application of non-ceramic
insulators in electrical transmission systems and substations will be
presented from both a developer's and user's viewpoint.  Subject areas
covered in the course will include a review of polymer matrix composite
materials and weathershed materials for non-ceramic insulator
technologies.  The most important properties of the materials will be
discussed.  Special emphasis will be placed on the insulator failure modes
which can develop either during manufacturing or in service.  Both
mechanical and electrical failure mechanisms in non-ceramic insulators
will be discussed and recommendations will be given on how to avoid them. 
Unique experimental techniques will be presented concerning the effect of
combined mechanical, electrical and environmental stresses on the
in-service integrity of the insulators.  In addition, the insulator
contamination problems, and field and laboratory test procedures will be
discussed with respect to traditional porcelain and composite insulators. 
This short course should provide a unique forum for the exchange of
experience between the users, manufacturers and researchers involved in
the non-ceramic insulator technology.
