MODULE DETAILS

Module 3:     Circuit Breakers and Switchgear

Nominal duration: 5 weeks (60 hours total time commitment)

This time commitment includes the preparation reading, attendance at each webinar (1 hour plus 15-30 minutes for discussion), and the time necessary to complete the assignments and further study.

MODULE PURPOSE

This module augments Module 2 (Power Distribution) and focuses on medium voltage (1kV-36kV) and low voltage switchgear.  It provides technical know-how in these areas generally not covered by university or college programs.

ASSESSMENT STRATEGY

To evaluate the achievement of the learning outcomes; written assignments, group projects and practical exercises are set.
