About This Training Course
This seminar is specifically designed to provide an advanced understanding of the principles of power system
protection design. Yet, via a progressive “building block” approach, this seminar has been specifically designed to
meet the learning requirements of those who presently have only a fundamental knowledge of protection
principles, while also considering advanced topics to 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
• The introductory material covers the basic principles of protection design, reliability, security and dependability
as well as the implementation of unit and non-unit protection schemes, and remote, local and dead zone back-
up schemes.
• With this grounding, delegates learn the principles of fault level calculation, including a comprehensive, but
easily comprehendible discussion of sequence components.
• The seminar proceeds to cover the application of over current and earth fault protection, including application
to transformers, parallel networks, and the need for directional facilities.
• The implementation of voltage and current transformers, to IEC60044, covers both the steady state and
transient requirements for these essential components, including the application of the (1+X/R) CT transient
requirement.
• Distance relay protection discussions cover fundamental design aspects, relay comparator characteristics and
load transfer implications. Protection signalling requirements, to meet regulatory requirements covers the
fundamental principles of distance relay permissive and blocking schemes as well as considering power line
carrier applications.
 Unit protection scheme discussions cover both the application of high impedance differential schemes and
biased low impedance differential schemes. In considering the latter with the specific application to transformer
protection, the aspect of phase angle correction, zero sequence current correction, CT connection and the
application of microprocessor based relays is considered in detail. The special application of high and low
impedance schemes to busbars is discussed. The application of unit protection to feeders covers the
implementation of feeder current differential relays.
• Short circuit protection of induction motors is considered, but since most electrical failures are actually the
result of previous overheat, this latter topic is especially considered in detail.
• Finally, the specialized requirements for the protection of synchronous generators are comprehensively
considered. This discussion includes high speed protection for actual generator faults, and also coordinated
slower protection philosophies for generator and power system events.
Learning Outcomes
This seminar is specifically designed to provide a comprehensive and in-depth understanding of the principles of
power system protection design. This seminar has been carefully formulated to provide a valuable insight into
power system protection design and principles for those more experienced in the discipline of protection design
while yet meeting the learning requirements of those who presently have a more limited knowledge of power
system protection principles.

Who Should Attend
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 other less directly associated areas of electrical power
system design. 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.
• Power System Network Operators, to ensure optimisation of network performance and operation
without compromising protection principles or risking inadvertent protection operators.
• 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 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 Engineers, to ensure the actual field installation of the protection scheme and associated
relay settings meets the design requirements.
• Field Technicians, to understand the importance of their role in installing, testing and maintaining
effective, reliable, dependable and secure protection systems.
• Project Managers, to ensure that the project implementation provides a safe and efficient
implementation of electrical design.

Mr. Barrie Moor
Principal Engineer at Power System Protection Training,
Australia
Experience:
• 39 years in the Queensland Electricity
• Transmission and Generation Supply Industries
• 30 years in the discipline of Protection Design
• 20 years in Post Graduate Electricity Supply System
Training
With over 39 years experience in the Queensland electricity supply industry, our principal engineer, the seminar
author and presenter, Barrie Moor, has been involved in the design, coordination and implementation of protection
schemes associated with Queensland’s HV and EHV transmission systems since 1981. Barrie also has extensive
experience with the protection of large generating plants having had responsibility for the protection of generators
at many of Queensland’s major power stations. From 2000 to 2007, Barrie filled the role of Senior Engineer
Protection Design, with statewide responsibility, leading Powerlink’s Protection Design Team. From 2007 to 2012, in
the role of Principal Consultant Substation Protection, and then Principal Engineer Investigations, Barrie provided
specialist Protection Design and Fault Analysis services to support the Asset Management and Operational Groups
within Powerlink. Barrie has 20 years experience within Australia and internationally (New Zealand, Singapore,
Malaysia, Thailand, Pakistan, UAE, Ghana) in the provision of university post graduate training on the design and
implementation of HV and EHV Transmission Protection Systems and also and Power Station Generator Protection
Systems. Barrie has presented a number of papers on various specialised aspects of protection design at conferences
both within Australia and internationally. Barrie represented Powerlink on CIGRE committee APB5, Power System
Protection and Automation, and served as a corresponding member on Cigre and IEE working groups on 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
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 standardising 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.
