Fault Analysis with Applied Symmetrical Components

PSA400 is a must course for electrical engineers, electricians and electrical engineering professionals who wanted to gain understanding how symmetrical component as a tool is used in Fault Analysis and Protective Relaying.

This course covers theory of the symmetrical components but more importantly explains how this analysis tool is applied in power system protection.

Course Outline

  • Per unit system
  • Phasors and perform phasor operations
  • Convert systems into per-unit quantities
  • Advantages of the per-unit system
  • Short-circuit fault types
  • Simplify complex circuits using a Thévenin equivalent circuit
  • Analyze the zero-, positive-, and negative-sequence components
  • Conversion between phase and symmetrical component values
  • Model of sequence impedances for transformers, generators, and transmission lines
  • How to draw sequence networks and calculate fault currents for different shunt and series fault types
  • Calculate symmetrical components for different types of faults
  • Calculate the voltage and currents for different types of faults
  • Series fault calculation
  • Voltage and current profile during faults (positive, negative, zero-sequence voltage)
  • Three-phase analysis of single-line-to-ground fault with various grounding methods (neutral grounding, wye-delta grounding, zig-zag transformer)
  • Commissioning, finding errors in CT and PT connections based on symmetrical component
  • Class exercises and manual calculations


Q: What is the format of this course?
A: Asynchronous learning that include recorded lectures you can access anytime 24 hours a day. The course include recorded lectures, quizzes to test what you learned, assignments to further challende your understanding and feedback from the instructor on your answers.

Q: Why asynchronous learning?
A: We belive this instruction delivery is better suited for busy professionals like yourself. This allows all the oppotunity needed to fully absorb the material and at the same time provides schedule flexiblity. Just think of the formal degress like MSEE offered online by recognized universities locally and abroad.

Q: What if I have questions?
A: There are Q&A sections in each lesson where you can ask questions and get answers directly from the instructor. You can also send emails to us.

Q: What if my questions are complicated?
A: We will create video lectures to answer your questions and upload them into the Q&A section. This will become a live repository of all questions from past and present students where everyone can learn from each others questions.

Q: What else can I expect from this course?
A: This course include discussion of theories, practical applications, manual calculations showing steps, demonstrations via software (excel, ETAP or SKM), correlation with actual projects design/experience of the trainer.

Q: How long do I have access to the course?
A: You have 8 weeks access to the course. Length can be extended for extensive courses.

Q: Can I use this training to claim for CPD points?
A: We will issue a course completion certificate. You can then use the certificate to claim for self directed CPD points credit. Please refer to PRC CPDAS website for the procedure to claim.
