Rotating electrical machines - Part 24: Online detection and diagnosis of potential failures at the active parts of rotating electrical machines and of bearing currents - Application guide

Scope

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.
