Rotating electrical machines - On-line partial discharge measurements on the stator winding insulation of rotating electrical machines
Rotating electrical machines - On-line partial discharge measurements on the stator winding insulation of rotating electrical machines
1 Scope 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 measur ing systems and methods detecting electrical PD signals. The same measuring devices and procedures can also be used to detect electrical sparking and ar cing phenomena.
NOTE The main differences between on-line measurements and o ff-line measurements are due to a different voltage distribution along the winding and various thermal and mechanical effects related to the operation, li...
