Rotating electrical machines -- On-line partial discharge measurements on the stator winding insulation of rotating electrical machines

PUBLISH DATE 2012

BSI PD IEC/TS 60034-27-2:2012

This part of IEC 60034, which is a technical specification, provides a common basis for:

  • measuring techniques and instruments;

  • the arrangement of the installation;

  • normalization and sensitivity assessment;

  • measuring procedures;

  • noise reduction;

  • the documentation of results;

  • the interpretation of results;

with respect to partial discharge on-line measurements on the stator winding insulation of non-converter driven rotating electrical machines with rated voltage of 3 kV and up.

This technical specification covers PD measuring systems and methods detecting electrical PD signals. The same measuring devices and procedures can also be used to detect electrical sparking and arcing phenomena.

NOTE The main differences between on-line measurements and off-line measurements are due to a different voltage distribution along the winding and various thermal and mechanical effects related to the operation, like vibration, contact arcing or temperature gradients between stator copper and stator iron core. Furthermore, especially for hydrogen-cooled machines the gas and the gas pressure is different for off- and on-line PD measurements.
