Dr. Nancy Frost

The focus of this presentation is the fundamental aspects of electrical insulation
materials, specifically for rotating equipment - generators and large motors. This talk 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 presentation help the audience to understand the critical working
aspects of electrical insulation materials. The “why” of dielectrics for their specific
applications. This knowledge can aid in maintenance decision processes, equipment
repair decisions, as well as educate those in the industry understand the tradeoffs in the
dielectric materials selection process.
