Presenter:   Gunter Baumgarten

Electrical insulating materials have a limited life span especial at elevated temperatures. The thermal class is an important criterion of the material. This presentation features the following aspects:

  • difference between thermal class and temperature index
  • relation to practical application
  • established methods and other possibility
  • why is there more than one TI
  • sense and nonsense of test- and endpoint criteria
  • aerobic and anaerobic environment
  • are short time analytical tests a shortcut for TI-testing

Examples are shown, results are presented and possibilities are discussed.
