ADMO Time Grading

Create and manage your tripping schedules for distance protection systems

The ADMO Time Grading module supports you in creating and maintaining your time grading schedules. Creating your tripping characteristics and verifiying the selectivitiy is becoming a lot easier. The module also enables you to easily reuse existing time grading schedules. Versioning provides a quick overview of the status (active, in planning, archived) of the different schedules.

If a time grading schedule is deactivated while it is being used as a reference in another time grading schedule, a warning will be displayed. All of your time grading schedules are available in overview mode, making their maintenance more convenient.
