Protection of low, medium and high voltage power systems requires an understanding of system faults and their detection as well as their safe disconnection from the power system. This course presents a comprehensive description of the concepts and principles of operation and application of protection schemes for various power system elements such as feeders, transformers, motors, buses and generators.

Learn about protection systems from a practical perspective and important functional aspects, such as the testing and coordination of protection systems. The course is specially designed for industries and utilities which depend on proper system protection for operational efficiency and minimizing damage to equipment.

After participating in this course, you will be able to:

Ø  Use your knowledge of protection techniques

Ø  Further your understanding of protective devices

Ø  Determine your own relay settings

Ø  Apply your awareness of recommended practices in protection schemes

Ø  Understand problems generally faced and develop solutions
