Why enroll

Participants join this course to clearly understand how power systems are protected and kept safe in real life, not just in textbooks. The course explains concepts in a simple and practical way, showing how protection schemes actually work in Indian power networks. Students learn the basics of protection, modern relays, and how different parts of the system work together during faults. This knowledge is very useful for careers in power utilities, transmission and distribution companies, power plants, EPC companies, and grid operation jobs. The course also helps students preparing for GATE, higher studies, and research. Overall, it prepares learners with practical, job-oriented skills to handle today’s challenges such as complex grids, renewable energy integration, and reliable power supply.

Course details

Power System Protection is a core course in the B.Tech Electrical Engineering curriculum at most state engineering colleges and NITs, while at IITs it is typically offered as part of the Power Systems stream and as an elective at the undergraduate level. The subject is also a common and essential component of almost all M.Tech programs in Power Systems across India. The M.Tech Power Systems curriculum is largely uniform among the older IITs, NITs, and state colleges, which collectively develop the human resources required for the country’s electric power supply industry. This course covers up-to-date technologies in power system protection, with strong emphasis on current practices followed in Indian power systems, and highlights the emerging challenges faced in this domain.
