The method of symmetrical components is used to simplify asymmetrical three phase voltages and current analysis by converting the unbalanced system into two sets of balanced phasors and a set of single-phase phasors, or symmetrical components. These sets of phasors are called the positive, negative, and zero sequence components.
An understanding of this method is essential for the understanding of fault analysis and modern day protection schemes. This course will provide you with the knowledge to comprehend the concept and how it is applied.
Who this course is for
- Maintenance Personnel working in the electrical power protection industry
- Very practical and down to earth. Fantastic. Thank You ~ Michael W
- Instructor was clear and concise. Course was at a great pace and well presented. The material was very informative ~ Terrel L
- This guy is amazing and explain stuff well. I hope he will keep making more technical courses to educate us better ~ H Al Radhwan
- I liked the way the professor prepared the class. It’s very easy to follow the content through each lesson. And I specially appreciate the last lesson which is calculations using symmetrical components. It’s a very helpful course for people involved in electrical power systems ~ Milton R
- I'm taking an electric transmission system relay course to complete my professional development hours. The course is very fast paced and it has been 30 years since I have done these types of calculations by hand. This course was a great refresher for the math behind symmetrical components and will help me stay up to speed in the relay course ~ K Vansickle
What you'll learn
- In this course, you will learn exactly what symmetrical components are, their main advantages, how manufacturers of equipment use it.
- You will learn how to use symmetrical components to simplify asymmetrical three phase voltages and current and understand fault analysis.
- Including Positive, Negative and Zero Sequence Components.
- You can later apply this knowledge to single phase to ground, two phase to ground, phase-to-phase, and three phase fault conditions.
- This course may be considered a prerequisite to the course "Short Circuit Analysis for High-Voltage Three-Phase Systems".
The student should have an understanding of the laws and theorems related to three phase electrical power systems.
