MODULE DETAILS

Module 4:     Power Systems Protection

Nominal duration: 4 weeks (48 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 has been designed to give plant operators, electricians, field technicians and engineers a better appreciation of the role played by power system protection. An understanding of power systems along with correct management leads to increasing plant efficiency and performance as well as increasing safety for all concerned.
