PROT 405: Industrial Power System Protection

Overview

Engineers who need a comprehensive understanding of the challenges and solutions for protecting industrial power systems should attend this course.

PROT 405 provides an overview of the principles and schemes for protecting medium-voltage overhead lines and cables, transformers, buses, generators, and motors, and it introduces the fundamentals of wide-area protection in industrial power systems. The course provides basic guidelines for relay application and settings calculation. It also reviews power system faults, industrial power system grounding methods, and instrument transformers.
