Digital Techniques for Relays

Digital technology of the Relay requires an understanding of system faults and their detection, as well as their reliable safe isolation from the system. This course presents comprehensive and systematic descriptions of the concepts and principles of application and operation of digital relaying schemes applied for various power system elements. In addition, the course enforces the concepts by presenting several actual case studies occurred on the relay.

This course is designed to review for the participant the fundamental concepts of digital techniques relaying, relay protection using symmetrical components. It advances to important issues regarding the protection, of transformers, generators, transmission lines, breaker failures, buses, motors and shunt capacitors.

The course curriculum is designed for electric power utility engineers, technicians and designers involved in the control, operation, and protection of electric power systems. It is also intended for consulting and manufacturing engineers as well as engineers with protective relaying relay supply companies.
