This course is traditionally introduced as part of the " UR relays application level-2 " course or the " Motor protection course "

The protection engineer will gain an in-depth understanding of themajor protective element algorithms for the M60. The review of a sample settings file in addition to Oscillography and event logs forspecific faults will aid in a complete understanding of how to apply theM60 and how the M60 should perform.

This course is designed for protection engineering staff responsible for Motor protective relay selection and settings.
