A New Standard for the Modern Liquid-Immersed Transformer

Presented by Richard P. Marek of DuPont Energy Solutions


Today, state of the art computer programs have extracted about as much cost as possible in pursuit of competitive designs, while still maintaining the highest standard of quality and reliability. High-temperature in liquid-immersed transformer applications 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 stategy.

High-temperature design has been around for many years operating on the fringe of the standards and lurking in the background. Since, almost by definition, the standards follow technology rather than lead the development, at some point a critical mass creates the need for a written document to structure and guide the future development of a new technology.

This presentation will discuss a newly published IEEE document that will finally standardize high-temperature liquid-immersed transformers. Complimentary to this new standard is the recently published IEEE document that defines the test procedures for determining the thermal class of an insulation system in a liquid dielectric medium.

Examples of typical and not-so-typical global applications for high-temperature liquid-immersed transformers will also be presented.


The Presenter:


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-immersed 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-immersed transformer standard, C57.154; and the dry-type loading guide, PC57.96.
