While this seminar is specifcally designed to meet the learning needs of newer protection engineers and technicians, it will also provide a valuable, comprehensive and in-depth understanding of the fundamental principles of power system protection design to meet the requirements of more experienced participants.

Know About Your Trainer

Our trainer 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, Our trainer 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, Our trainer provided specialist Protection Design and Fault Analysis services to support the Asset Management and Operational Groups within Powerlink.

Why Should You Attend This Training

THIS SEMINAR HAS BEEN SPECIFICALLY PREPARE 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.
• Field Technicians, to understand the importance of their role in installing, testing and maintaining effective, reliable, dependable and secure protection systems.
• 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 does meet the design requirements.
• Maintenance Engineers, to ensure that power system protection is not compromised as plant is removed from service during maintenance.
• Planning Engineers, to identify the difficulties in providing protection for various power system configurations under review.
• Project Managers, to ensure the project execution process optimises coordination between protection design and the overall project implementation
