IEEE DEIS Web Videos

The Institute of Electrical and Electronic Engineers, Inc. Dielectrics and Electrical Insulation Society Website (IEEE DEIS Web) has been placed historical educational videos from the 1960s on the website under http://ewh.ieee.org/soc/deis/education/all-education-material.html. When finished, there will be more than 50 educational videos available for viewing by IEEE DEIS members. The videos each have a 2-5 minute preview for non-members. The videos available as of July 21, 2009, are:

- “Rotating Machinery Workshop:” the first video about one hour in length that describes all of the major insulation tests from their basic principles.
- “Streamers in Liquids: Basic Phenomenon:” This short video of about 20 minutes describes semi-conductive and conductive streamers within insulating oils.
- “Fundamentals of Motor Insulation for Repair Shops Part 3:” This video of about one hour and fifteen minutes discusses proper insulation systems for repaired electric motors, in particular the forces on the coils in an operating motor and the proper securing of the insulation system as described in this week’s tech tip.
- “Turn Insulation Aging of Motors Exposed to Fast Pulses of Inverter Drives:” Describes the breakdown of motor insulation systems in inverter applications. Runs about 18 minutes.
- “Utilizing Reduced Build Concepts in the Development of Insulation Systems for Large Motors:” this 18 minute video discusses the concept of using thinner insulation systems for improved thermal transfer. It requires improved insulation materials.

Additional videos will be placed a minimum of one or two per week.
