Description
Summary:The possibilities of application of DTA and TG are illustrated in an investigation of the changes in quality of high-voltage insulation, one of which is an organic filler-modified epoxy resin gum. Thermal analysis can be used to assess the degree of degradation, as presented on the examples of Relanex and Sklotextit stressed by temperature, and also to observe the course of hardening of materials and hence to follow the technology in the course of production. The possibility of use of this method is shown for electric rotating machines without damage to their insulation system. The possibility of the use of DTA and TG is presented for determination of the slope of the straight line plot of the lifetime of an insulation.
