Description

PROT 401
Course Information

ePROT 401 provides an overview of the principles and schemes for protecting power lines, transformers, buses, generators, and motors, and introduces the fundamentals of wide-area protection. The course provides basic guidelines for relay application and settings calculation. It also reviews basic power system concepts and describes instrument transformers.

This self-paced virtual course combines instruction from SEL University instructors with exercises and provides opportunities to connect with instructors when you have questions or need further guidance. eLearning licenses will expire one year from the purchase date.

The duration of the complete ePROT 401 course is 39 hours (38 hours, 55 minutes). In all, there are 15 topics/sections and 11 exercises. The course includes a 10-minute introduction with helpful information about the course format, how to mark a section as complete, video player use, self-check questions, etc.

The online course format has two folders of content:

  • Sections—recordings of the lecture and downloadable exercise files
  • Resources—course manual with notes, solutions to the exercises, additional links, and a link to email instructors for help

CEUs or PDHs will be available on a section basis. A link to the certificate will appear next to each section once that section is complete.

Audience

Engineers who need a comprehensive understanding of the challenges and solutions for protecting electrical power systems would benefit from this online, self-paced, eLearning course.

Course Objectives

At the conclusion of this course, students can:

  • Identify the challenges and solutions to power system protection problems.
  • Select the appropriate protection schemes for various applications.
  • Analyze power system faults for balanced and unbalanced conditions using symmetrical components.
  • Describe current and voltage transformers and their impact on protection scheme performance.
  • Identify, apply, and calculate settings for distribution and transmission line protection schemes, including overcurrent, directional overcurrent, distance, and pilot protection schemes.
  • Identify, apply, and calculate settings for transformer, bus, and breaker failure protection schemes.
  • Identify, apply, and calculate settings for generator and motor protection schemes.
  • Identify and apply wide-area protection schemes, such as power swing blocking, out-of-step tripping, and load shedding.

Student Background and Knowledge

A degree in electrical engineering or equivalent experience is recommended. In addition, we recommend that you have:

  • A basic knowledge of power systems.
  • A working knowledge of ac three-phase electrical circuits, trigonometry, basic calculus, complex numbers, and phasor concepts.

Recommended reading:
