There are more than 18,500 generators at more than 6600 generating stations rated more than one megawatt in the US alone. Transformers sit in the background of our everyday lives transferring this power to our businesses, our homes and to every modern convenience we have become accustomed to. By 2035, the global demand for this energy is expected to increase by 36% bringing with this expansion certain challenges for fit and purpose. New materials and techniques certainly will become more important and DuPont will be present with its portfolio of unique high-temperature products, having played a central role in supporting the development of high-temperature transformers and the standards that govern these products. Today, state of the art computer programs have extracted about as much cost as possible in pursuit of competitive designs for liquid-immersed transformers, while still maintaining the highest standard of quality and reliability. But standard materials inherently limit size or weight reduction and life extension is limited to lowering the temperature rise and correspondingly increasing size and weight. High-temperature insulation offers a new avenue to explore the possibilities of matching an application with optimized cost and is now one of the few opportunities available for a true step-change in design strategy for life extension, increased capacity or smaller size. High-temperature design has been around for many years operating on the fringe of the standards and lurking in the background. Now the standards are in place and available to shape development in this area. This presentation will discuss examples of typical and not-so-typical global applications for high-temperature dry-type and liquid-immersed transformers. Examples and case histories will be presented to illustrate some of the many successful uses for high-temperature insulation in an effort to broaden the industry's concept of the ubiquitous transformer.

- Learn how high temperature transformers can be designed to resist significant mechanical stress
- Become familiar with case studies that demonstrate how high temperature transformers can be used to solve tomorrow's challenges
Rick Marek received his BSEE from Purdue University in 1970 and has been employed with DuPont since 1998. His previous work experience includes a total of 28 years with Hevi-Duty Electric, National Industri and ABB in transformer and specialty power supply manufacturing. He worked as an engineer in design, test and development for special magnetics, dry-type, epoxy cast and liquid-filled transformer products. For 20 of those years he served as a design or engineering manager. He is a senior member of IEEE where he has been active in the Transformers Committee, various subcommittees and numerous working groups since 1982. Rick has served as chairman of the harmonic loading guide, C57.110; the high-temperature liquid-filled transformer standard, PC57.154; and the dry-type loading guide, PC57.96. He is an IEC TC 14 delegate for the US Technical Advisory Group and is active in working groups and maintenance teams related to transformers. He is also the convenor of the high-temperature liquid-filled transformer standard IEC 60076-14.
