| Brief description of the Unit |
| This unit extends learning of power system analysis to provide in-depth knowledge and understanding of power system protection. Students will be introduced to instrument transformers, fundamentals of relaying, overcurrent protection and coordination, directional overcurrent protection, differential protection, distance protection, and distributed generation protection. The development and challenges related to the field of power system protection will be covered by linking theory to real industry examples. |
