J. Keith Nelson


Dr. Nelson was the Philip Sporn Professor of Electric Power Engineering at Rensselaer until 2009, having served as Head of the Department of Electric Power Engineering from 1987 to 2001. Previously he had been Manager of High Field Technology Programs at the General Electric Corporate Research and Development Center in Schenectady, NY, after serving as a faculty member at the University of London in the UK. His early career and training had been in the utility industry with Eastern Electricity in the UK. He holds degrees from the University of London and is a Fellow both of the IEEE and the IET. Keith Nelson has been very active in the Institute of Electrical and Electronic Engineers, and is past President of the IEEE Dielectrics and Electrical Insulation Society. He was elected as a Director of the IEEE in 2010. He has acted extensively as an industrial consultant to numerous organizations and is an evaluator for the Acceditation Board for Engineering and Technology (ABET).. Dr. Nelson has been the recipient of many awards from professional organizations such as the Institution of Engineering and Technology {formally the IEE} (UK), the Institute of Electrical and Electronic Engineers (US), the Edison Electric Institute, the Royal Society, and the Japan Society for the Promotion of Science. In 2007, he was awarded the "Outstanding Professor Award" by the Rensselaer Engineering School, and more recently (2017), The Maquis Lifetime Achievement Award. A full Curriculum Vitae is available. A pictorial portrait may also be viewed to depict his life and times.


The primary area of interest involves the physical phenomena of power system equipment. This embraces dielectric phenomena and high voltage technology, physical electronics, gas physics, and, more recently, the application of superconductivity to power apparatus and the development of nanodielectrics. As an experimentalist, Dr. Nelson is particularly interested in the development of computer-based diagnostic instrumentation for power plant (currently transformers and generators). Acoustic and optical methods; as well as artificial intelligence are often invoked in this arena. Computer numerical modeling of the physical processes involved is often an important element in this work. The involvement in high-voltage and transient phenomena also includes a strong interest in electrostatics. Interest has centered both on the understanding and mitigation of unwanted electrostatic effects (e.g. streaming electrification) and also on the utilization of electrostatics for such things as precipitators.

Research Specializations

  • Streaming Electrification and ECT in liquids
  • Generator Insulation Diagnostics
  • Ultrasonic interrogation of insulating structures
  • Artificial intelligence applied to partial discharge analysis
  • Development and application of nanodielctrics
  • Superconducting quench phenomena
  • Distributed generation and islanding issues
  • Large scale computer modeling in connection with these activities.

Since 2002, most of Professor Nelson's research activity has centered on the development of nanodielectrics as a new class of insulating materials. This activity is encapsulated in a new book entitled "Dielectric Polymer Nanocomposites" which was published by "Springer-Verlag" in early 2010.
