Contact Hours 3 lecture hours/week, half course Prerequisites ECE4464a Topics Philosophy of power system protection. Operating principle of relays. Relaying principles such as differential, distance, phase comparison and directional comparison protection. Protection of distribution circuits using instantaneous and inverse time over current relays. Protection of looped circuits using directional over current relays. Protection of transmission lines using distance, differential, and phase- and directional-comparison relays. Protection of transformers and busbars. Protection of generators and motors. Protection aspects of power system operation. Textbook S.H. Horowitz & A.G. Phadke, Power System Relaying, 2nd edition, Research Studies Press, 1999, ISBN 0 471 95887 5. References J.L.
