Abstract

The innovative insulating tape for rotating machines shows advantages concerning the electrical and mechanical strength as well as its thickness and thermal conductivity. In this paper the new developed mica tapes should be tested with respect to the thermal behaviour of the end corona protection and voltage endurance of various types of used mica paper. For this reason a test series of different defined insulation systems was carried out to test the temperature rise and a long time test with increased voltage stress was applied. The results were evaluated within a statistical analysis and lifetime charts.
