Relaying and System Protection for Electric Utilities - Volume III:Line Protection
In Relaying and System Protection for Electric Utilities - Volume III:Line Protection, you'll learn ...
- The relaying schemes and processes used to protect transmission lines
- The application of both non-directional and directional overcurrent relays
- Distance relaying schemes as they apply to transmission lines
- The predominate communications channel types in use today for pilot relaying
Overview
This course is the third in a series of five courses on the design of relaying and system protection programs for electric utilities. These courses describe the fundamental concepts of electric system protection and provide detailed examples of the application of relaying. In most cases, the material is based on electromechanical relays to give the reader a strong understanding of current relaying practices.
This course explains the practices involved in protecting transmission lines and includes overcurrent relaying, distance relaying, and pilot relaying.
This series is divided into five separate courses. Each course essentially stands on its own, and the courses do not necessarily need to be taken in the order listed. However, for a thorough understanding, it makes sense to take the courses as presented.
Learning Objectives
Upon completion of this course, participants will be able to:
- Identify the relay schemes used for line protection.
- Determine the settings for a time-overcurrent relay.
- Explain the application of a directional overcurrent relay.
- Apply appropriate TOC setting methodologies.
- Distinguish the types of distance relays used in line protection.
- Explain the advantages of a mho relay.
- Determine appropriate settings for distance relays.
- Describe the advantages of pilot relaying.
- Explain how a POTT relaying scheme operates.
- Identify communications channels used for pilot relaying.
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 35 questions. PDH credits are not awarded until the course is completed and quiz is passed.
