Presented By: Dr. Nancy Frost

Abstract:
The focus of this short course is the fundamental aspects of electrical insulation materials.
The main focus will be rotating equipment, but transformers, cables as well as transmission and distribution needs will also be discussed. This general course will cover basic components of an insulation system, material selection criteria, review of intrinsic properties as well as aging parameters. Major test methodologies and standards used in selecting and qualifying insulation systems will be discussed.
It is intended that this short course help the novice understand the critical working aspects of electrical insulation materials. This knowledge can aid in maintenance decision processes, equipment repair decisions, as well as educate those in the industry to understand the tradeoffs in the dielectric materials selection process.

Presenter’s Biography:
Dr. Nancy Frost is a Dielectrics Engineer with dual roles as President of Frosty’s Zap Lab, LLC, her dielectric materials R&D testing laboratory, and with Gerome Technologies as a Materials Engineer. She is focused on investigating aging mechanisms of dielectrics, and has given over 100 presentations and courses over the last two decades.
Dr. Frost has experienced the electrical insulation business from the points of view of vendors, customers, utilities and manufacturers. She has had the unique opportunity to see many insulation system designs and manufacturing styles, as well as a variety of aging techniques.

Presented By: Mr. Lars Arvidsson
General Manager VPdiagnose

Abstract:
This course describes considerations/methodologies used for e.g. transformer condition assessments and diagnostics that go far beyond the present standard methodologies. Gas formation is affected by a large number of factors that are not addressed in the present standards.

Who Should Attend?
Asset managers, and operation managers responsible for condition assessment of critical components in the electrical system
• Industry experts, Consultants, and Insurance specialists looking for more advanced and above all more accurate and efficient tools to assist and support their customers.
• People responsible for sampling and testing transformer oil.

Presenter’s Biography:
Lars Arvidsson is a Master of Science in Chemical Process Engineering and graduated in 1979 from the Lund University of Technology In Sweden. He founded VPdiagnose in 1994 and is the general manager. VPdiagnose is a completely independent laboratory dealing with machine diagnostics in general and transformers/reactors etc in particular. He specializes in the diagnosis based on state-of-the-art transformer testing technology beyond that of the International standards. He has over 40 years of involvement in the machine diagnostics areas and was the team leader when the “corrosive sulfur” problem was solved in 2013.
Lars is a member of Cigre and of IEEE and has recently been upgraded to “Grandfather 2.0”.

Presented By: Dr. Nigel Hampton

Abstract:
This course describes the most important factors that determine the electrical stress and strength in energy cables. Understanding the stress and strength enables the design of energy cables for longevity and reliability. It also provides a framework for managing the legacy grid. The topics include accessories & cables, basic construction elements, ac & dc voltages, degradation of the electric strength, and impacts on real-world applications

Who Should Attend?
Engineers and Field personnel responsible for specifying cable systems
• Asset managers, operation managers responsible for condition assessment of critical components in the electrical system
• Industry experts looking at new technological tendencies in the field testing arena
• Consultants who are looking for more advanced and efficient tools to assist and support their customers

Presenter’s Biography:
Dr. Hampton was born in the United Kingdom. He received his bachelor’s and doctoral degrees in Physics from the University of Bath. After receiving his doctorate, he undertook two years of postdoctoral research into the dielectric properties of ceramic and glassy dielectrics over a wide range of frequencies.

In 1988, Dr. Hampton joined the R & D laboratories of BICC Cables Ltd., located in North Wales, whereupon he earned a master’s degree in Polymer Engineering from Manchester Polytechnic. In 1991, Dr. Hampton joined the Supertension Cable business of BICC Cables, southeast of London. Over the next nine years, he worked within the HV & EHV cable business, building a number of internationally respected research programs. During this period, he pursued interests in the fields of HVDC, cable accessories, XLPE cables, applied statistics, and life analysis. Between 2001-06, Dr. Hampton had global responsibility for managing the technical and market activities for power cable materials (insulations, semicons and oversheaths) within Borealis AB in Sweden. In this role, he was involved in R&D innovation, customer support, and collaborative programs. Dr. Hampton worked at the National Electric Energy Testing, Research, & Applications Center from 2006 to 2021, where he developed and managed a large variety of projects related to the high field dielectric and performance characteristics of materials used in all parts of the electric utility industry. He also participates in a variety of industry technical organizations related to this field and is currently developing instructional programs related to the design and application of high voltage dielectrics, with a particular focus on MV, HV, & EHV power cable systems.

Dr. Hampton joined the Engineered Materials group of UL in October 2021 with global responsibility for Market Development for Cable Systems for Energy and Utilities.

Dr. Hampton is the author/co-author of more than 97 technical papers/presentations and is the holder of 18 patents or patent applications.
