Dielectric dissipation factor measurements on new stator bars and coils

Dielectric dissipation factor measurements of 20129 new form-wound stator bars or coils of rotating machines, varying from a rated voltage of 6 kV up to 27 kV inclusive and a core length from 520 mm up to 8700 mm inclusive, which were produced in the period 1960 up to 2016 inclusive, were collected and analysed in relation to the influence of rated voltage, core length, insulation system, manufacturer and guarding technique. During the webinar results of this analysis will be presented
