scope:

This part of IEC 60034-27 series deals with on-line PD measurements and provides a common basis with standardized procedures if possible 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 interna- tional standard 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.
