Abstract

Motorette test based on IEEE Std. 275 have been usually adopted as a thermal evaluation method for rotating machinery insulation. There are some problems in performing thest tests. The tests required a considerably time. And, as the tests predict the life at an operational temperature by an extraporation method based on the data at higher temperatures, there is a possibility of missing a change in the temperature dependence of the thermal degradation mechanism. Therefore, the thermal life evaluation method by an EGA-GC (Evolved Gas Analysis-Gas Chromatograph) was examined in comparison with the motorette test method.
