Power System Protection is a very common core course for BTech in Electrical Engineering for State colleges and NITs. In IIT it is a part of the power system subject and an elective subject for BTech. Power System protection is almost common to all M tech programs in Power System in India. Note M Tech Power System curriculum is common to most of old IITs, NITs and state colleges which caters human resource for the whole electric supply systems of the country.This course will cover up-to-date technology in the field emphasizing the current practice in Indian systems and also make aware of the current challenges in the system in this domain.

Intended audience: B TECH (ELECTRICAL), B TECH (ELECTRICAL AND ELECTRONICS), M. TECH (ELECTRICAL)

Prerequisites: POWER SYSTEM ENGINEERING
