ENGINEERING IN MINING – POWER SYSTEM PROTECTION

INTRODUCTION:

Electrical power system operates at various voltage levels from 415 V to 400 KV or even more. Electrical apparatus used may be enclosed (e.g., motors) or placed in the open (e.g., transmission lines). All such equipment undergo abnormalities in their lifetime due to various reasons. To achieve safety of the system, electrical equipment has to be monitored to protect it and provide human safety under abnormal operating conditions.
This course is designed to help students to gain theoretical and applied understanding of power system protection, Protection schemes for various power system configurations, Fault current calculations, Protection of generators, transformers, transmission lines, bus bars and feeders. After completing this course, students will gain professional knowledge on the emerging issues and challenges in the power system protection field related to increasing penetrations of distributed generation and intelligent, self-healing networks.
