Overcurrent protection

Any engineer who is involved with design or operation of overcurrent protection schemes for utilities or industry will benefit. Skills taught in this course include coordinating fuses, sectionalizers and reclosers.

Target audience

Suited for any engineer who is involved with the design or operation of overcurrent protection schemes for utilities or industry will benefit. The course will be more beneficial for those who have a working knowledge of overcurrent protection devices.

Learning objective

At the end of this course, students should be able to coordinate fuses, sectionalizers and reclosers.

Course abstract

This course guides students through several concepts and real-world examples as well as providing students with a comprehensive reference manual. A major component of this course includes hands-on-learning with time-current coordination software files distributed to attendees. Instructions on downloading the software will be provided in advance of the course.

The reference materials binder prepared for this course is a thorough resource written by Eaton Power Systems engineers and includes practical information to help you accomplish your day-to-day objectives.
