PROT 405: Industrial Power System Protection (India)


PROT 405 is designed for engineers who need a comprehensive understanding of the challenges and solutions for protecting industrial power systems. This course provides an overview of the principles and schemes for protecting medium-voltage overhead lines and cables, transformers, buses, generators, and motors, and introduces the fundamentals of wide-area protection in industrial power systems.

You will learn basic guidelines for relay application and settings calculation. You will also review power system faults, industrial power system grounding methods, and instrument transformers.
