About The Course

This training course is designed for Utility and Power System Professionals.


The participants will learn from a basic understanding of the elementary concepts and fundamental principles of Power System Protection through to an in-depth and comprehensive understanding of Distribution, Transmission, Power System and Power Station Protection.

Learning Outcomes

  • 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 PUTT and POTT schemes and blocking schemes as well as considering power line carrier applications.
  • Specialized distance relay application aspects, including mutual coupling, teed feeder, Zone 3 back-up and Switch OnTo Fault (SOTF) logic are then discussed.
  • 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.
  • Finally, in considering generator protection, delegates will learn the principles of high speed protection for generator stator and rotor faults, while developing an appreciation for the philosophy of actually tripping as slowly as possible as applied to protecting generators from local and remote events such as overload, unbalanced loading, over and under excitation, over and under frequency, reverse power, and pole slipping.

Expert Course Faculty

With over 39 years’ experience in the Queensland electricity supply industry, our principal engineer, our trainer has been involved in the design, coordination and implementation of protection schemes associated with Queensland’s HV and EHV transmission systems since 1981.


He has also an 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, our expert 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, he provided specialist Protection Design and Fault Analysis services to support the Asset Management and Operational Groups within Powerlink.


He has 25 years’ experience within Australia and internationally in the provision of university post graduate training on the design and implementation of HV and EHV Transmission Protection Systems and Power Station Generator Protection Systems.


Our expert has presented a number of papers on various specialized aspects of protection design at conferences both within Australia and internationally.


He 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.
