Distribution System & Transmission Line Protection

PROT500 is an extensive course covering almost all commonly used protection schemes applied to very large industrial facilities, utility distribution systems and transmission lines.

This course is a must for electrical engineers, electricians and electrical engineering practitioners seeking to further their knowledge in the field of relaying, protection & control of power systems.

This course incorporates traditional as well as modern techniques in power system relaying. Students will learn from live lectures from a practicing professional engineer with international experience. This course will discuss theory, exercises as well as practical applications.

About the Trainer

Ryan is a registered Professional Engineer in United States, Canada and the Philippines. He has over 16 years of working experience in industrial sectors, utility power and renewables. At present, he is a Senior Protection & Control Engineer working for one of United States leading power engineering firm. He is a member of the IEEE Power & Energy Society.

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.
