Description

Power system protection is very important for generation, transmission, utilities and industrial electrical distribution networks, because it limits the damage in electrical networks caused by short circuit and other type of faults. The course contains the different types of relays, the function of each relay, the basic requirements of the protective relays and how to protect the electrical network components such as transformers, generators, motors, feeders, distribution and bus-bars.

Course Objectives

Upon completion of the course, participants will be able to:

  • To know the basic requirements of protective relays and the different types of faults in the electrical network
  • To know the different types of relays and principles of operation of each type
  • To learn how to protect the generators, transformers , feeders , bus-bars ,motors and distribution circuits
  • To know what is the primary and secondary protection

Case Study

  • Examples and case studies will be Appropriate during the training sections. Delegates should come to the training with an example of a project they may wish to undertake and deliver in future to be discussed. Delegates will be asked to work in groups to practice planning skills and learn various concepts and techniques.

Course Methodology

A variety of methodologies will be used during the course that includes:

  • (30%) Based on Case Studies
  • (30%) Techniques
  • (30%) Role Play
