Length: 50 pages

This course is the fourth 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.

Volume IV describes the relaying and protection schemes for large substation transformers and the associated substation bus work.

There are five separate courses in this series.

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.

Specific Knowledge or Skill Obtained

This course teaches the following specific knowledge and skills:

• The issues associated with transformer protection
• How current transformers connect to a differential protection scheme
• How to protect a transformer for magnetizing inrush
• How to apply variable percentage differential relays to bus protection
• How differential relays may be advantageous in bus protection
• The operation of a high-impedance voltage differentiation scheme

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 20 questions. CPD credits are not awarded until the course is completed and quiz is passed.
