PROT 401: Protecting Power Systems for Engineers

Overview

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

PROT 401 provides an overview of the principles and schemes for protecting power lines, transformers, buses, generators, and motors, and introduces the fundamentals of wide-area protection. The course provides basic guidelines for relay application and settings calculation. It also reviews basic power system concepts and describes instrument transformers.
