MODULE DETAILS

Module 10: Power System Protection  

Nominal duration: 6 weeks (72 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 examines the electrical power system protection and its applications. This module covers protection system components, a detailed study of operating principles of circuit breakers, protection relays, fuses and other protection devices, understanding specifications and selecting protection devices for various applications, specifying types, size, and configuration schemes.  Also it covers relay settings, unit protection systems, protection systems specific to equipment such as transformers, lines, machines etc.
