Abstract :
Time-temperature tests as a means of measuring losses in electrical machines are described in this paper, and some of the results which have been secured with such tests are described. The method consists principally in determining by test the initial slope of the time-temperature curve of some part of the machine, immediately after a steady load is thrown off. In this paper, application to the analysis of losses in turbine generators is described, although the method can be applied to other electrical apparatus.
