Description

Course Information 

Symmetrical components knowledge is an essential tool to understanding faults in the power system and how digital protection algorithms work. In ePROT 200, students will learn the fundamentals of symmetrical components, be exposed to theoretical and real-world examples to help them gain experience with the method, and apply that knowledge to analyzing and troubleshooting faults and problems on the power system.

This is a 13-hour self-paced virtual course. eLearning licenses will expire one year from the purchase date.

Audience

Utility and industrial engineers and technicians who need to learn about the fundamentals of symmetrical components and how they are used to calculate fault currents and commission protective relays would benefit from this eLearning course.


Agenda

  • Phasors
  • Per-Unit System
  • Fundamentals of Symmetrical Components
  • Sequence Impedances
  • Sequence Networks and Fault Calculations
  • Series Fault Calculation
  • Sequence Components and Commissioning
  • Class Exercises

Note: This course teaches fundamental knowledge but does not provide hands-on experience with SEL relays.

Course Outcomes

At the conclusion of this course, students will be able to:

  • Define phasors and perform phasor operations.
  • Convert systems into per-unit quantities.
  • Identify and define advantages of the per-unit system.
  • Define short-circuit fault types.
  • Simplify complex circuits using a Thévenin equivalent circuit.
  • Identify the zero-, positive-, and negative-sequence components.
  • Convert between phase and symmetrical component values.
  • Determine sequence impedances for transformers, generators, and transmission lines.
  • Connect sequence networks and calculate fault currents for various shunt and series fault types.
  • Identify symmetrical components for different types of faults.
  • Calculate voltage and currents for different types of faults.
  • Identify errors in the CT and VT wiring based on measured symmetrical components.

Student Background and Knowledge

Before you take this eLearning course, we recommend that you have a working knowledge of ac three-phase power systems.
