IEC/TS 60034-24:2009 is applicable to the on-line detection and diagnosis of failures at the active parts of multi-phase rotating electrical machines (induction and synchronous machines) and of bearing currents. The failure analysis includes
- inter-turn faults;
- phase-to-phase short-circuits;
- double earth faults and single earth faults of motors with earth connection of the star-point;
- static and dynamic eccentricities;
- cage imperfection or defects (e.g. broken bars or end-rings);
- bearing currents.
