Overcurrent Protection Fundamentals
This online engineering PDH course provides rules for time/current relay grading, IDMT protection characteristics, protection relay connections, as well as directional and ground protection.
Relay protection against high current was the earliest relay protection mechanism to develop. From this basic method, the graded overcurrent relay protection system, a discriminative short circuit protection, has been formulated. This should not be mixed with ‘overload’ relay protection, which typically utilizes relays that function in a time related in some degree to the thermal capacity of the equipment to be protected.
This 5 PDH online course is suitable for engineers with a desire to understand overcurrent protection fundamentals.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding the rules for time/current grading
- Learning about IDMT overcurrent protection curves
- Learning about grading relay-relay, fuse-fuse and fuse-relay
- Learning about protection relay connection
- Learning about directional and ground fault protection
In this professional engineering CEU course, you need to review the course document which is based on relevant ANSI, IEEE and IEC standards and widely adopted industry practice of setting overcurrent protection relays.
Once you complete your course review, you need to take a multiple-choice quiz consisting of thirty five (35) questions to earn 6 PDH credits.
Upon successful completion of the quiz, print your Certificate of Completion instantly. (Note: if you are paying by check or money order, you may print your Certificate of Completion after we receive your payment.) For your convenience, we will also email you your Certificate of Completion. Also, you can log in to your account at any time to access and print your Certificate of Completion.
