Over deze norm
NEN-EN-IEC 60034-27-3 provides guidelines for the test procedures and the interpretation of test results for dielectric dissipation factor measurements on the stator winding insulation of rotating electrical machines. These guidelines are valid for rotating electrical machines with conductive slot coatings operating at a rated voltage of 6 kV and higher. This standard applies to individual form-wound stator bars and coils outside a core (uninstalled), individual stator bars and coils installed in a core and complete form-wound stator winding of machines in new or aged condition. This International Standard applies to all kind of vacuum impregnated or resin-rich (fullyloaded) taped bars, coils and complete windings. It is not applicable to non-impregnated individual bars and coils or non-impregnated complete windings. Requirements for the dielectric dissipation factor characteristics of individual form-wound stator bars and coils of machines with rating voltages from 6 kV and higher when tested with 50 Hz or 60 Hz alternating voltages are given.
