- Designed for Utility and Power System Professionals.
- This is a generic seminar not focused on any particular protection relay manufacturer, product or product type.
- Taking attendees from a basic understanding of the elementary concepts and fundamental principles of
Power System Protection through to an in-depth and comprehensive understanding of Transmission, Power System Protection.
Seminar Philosophy
Because of the progressive building block approach, this seminar will assist …
- Both experienced and inexperienced protection design technicians and engineers.
- Those whose day to day work involves them in the application of protection design, coordination and relay setting.
- And also those in less directly associated areas of power system protection design.
What You Will Learn
This seminar is specifically designed to provide a comprehensive understanding of the principles of power system protection design. Via a progressive “building block” approach, this seminar proceeds from the basic concepts, such as security, reliability and duplication of power system protection through to a comprehensive consideration of protection of the transmission system and power station plant. Thus, this seminar is specifically designed to meet the learning requirements of those who presently have only a fundamental knowledge of protection principles,while, via a progressive approach, also considering more advanced topics to thus provide a valuable insight for those more experienced in the discipline of power system protection design. Hence, this seminar will assist both those whose day to day work involves them in the application of protection design, coordination and relay setting, and also those in less directly associated areas of electricity system design.
Who Should Attend
This seminar has been prepared specifically to meet the requirements of:
- Protection Design Engineers, to identify protection implications and to ensure design, coordination and relay setting principles provide the necessary levels of speed, security, dependability and safety
- Planning Engineers, to identify the difficulties in providing protection for various power system configurations under review
- Maintenance Engineers, to ensure that system protection is not compromised as primary and/or secondary system plant is removed from service during maintenance
- Circuitry Design Engineers, to ensure that protective schemes are implemented in a manner to provide optimum performance
- Commissioning and Project Management Engineers, to ensure the actual field installation of the protection scheme and associated relay settings meets the design requirements
- Commissioning and Project Management Engineers, to ensure the actual field installation of the protection scheme and associated relay settings meets the design requirements
- Technicians, to understand the importance of their role in installing, testing and maintaining effective, reliable, dependable and secure protection systems

WITH RECENT SEMINAR FEEDBACK:
- “Of the 5 training courses that I have been on, this one has been the best”
- “Barrie Moor kept it interesting, excellent presentation skills”
- “Great presentation, learnt a lot !!”
- “Barrie was very knowledgeable. He made the difference”
- “Attended seminar conducted in UAE. It was an amazing experience”
- I have attended your training in PC Karachi and it was a very wonderful training.
- Thank you so much, as we encounter with problem in REF scheme in one of our Sub station that CT ratio was different and multiple grounds observed in CT side. Your valuable comments will help us to fix this problem.
LINKEDIN TESTIMONIALS:
- I have now completed a couple of seminars / courses (Fundamentals of Power System Protection and Distance Protection training at QUT) with Barrie and once again could not ask for more.
Barrie is an expert in Power Systems Protection and spares no effort to pass on his knowledge, striving to share his extensive knowledge in the topics at hand, Barrie impresses all.
I will not hesitate to take another training course lectured by Barrie. I look forward to the next opportunity in power systems protection run by Barrie Moor. - Barrie is the best protection engineer I have had the pleasure to work with… They do not make protection experts like Barrie anymore…
- Having worked with Barrie on numerous projects and whilst standardizing Control Systems interface designs to protection schemes and plant, as well as experiencing Barrie’s protection systems and schemes training, I can readily attest that Barrie is an authority in the field of protection. His knowledge across all levels of protection (systems, design, theory) and ability to communicate (design, training) are astounding. Credit well deserved.
