EEA Electricity Engineers' Association

The EEA is pleased to announce the release of the new Power System Earthing Course in collaboration with Mitton ElectroNet.

Delivered through a blend of online theoretical learning followed by a Mitton ElectroNet-led workshop, the course gives attendees an understanding of

1. the purpose and scope of power earthing systems
2. the processes and methods of earth system design
3. how to perform an assessment of an earthing systems and provide options for risk mitigation

Through the course, learners should be able to:

• Evaluate an earthing system design against safety standards and statutory requirements
• Apply a whole-of-life philosophy and safety-in-design controls to the design of earthing systems
• Explore and communicate a range of solutions to earthing system problems

WHO SHOULD ATTEND

The course content and structure are tailored to attendees who have a basic understanding of electrical theory and wish to extend this knowledge into the field of power system earthing.
The course is suitable for technical engineers, planning engineers, engineering managers, project managers, electrical tradespeople and contractors in the generation, transmission, and distribution sectors.

COURSE SCHEDULE

It is recommended that participants begin the online course two weeks prior to the scheduled workshop.

Workshops are planned for:

• Wellington - Friday 24 September 2021
• Christchurch - Friday 15 October 2021
• Auckland - Date to be confirmed

• 1.1 Demonstrate the problem that earthing systems are designed to solve
• 1.2 Demonstrate the impacts of earthing system failure on people and property
• 1.3 Describe the philosophical objectives of an earthing system
• 1.4 Describe the theoretical tools of trade for earthing design
• 1.5 Discuss the impacts of legislation on power system earthing design

• 2.1 Describe how earthing system design may be applied across an asset lifecycle
• 2.2 Describe how safety in design controls may be applied across an asset lifecycle
• 2.3 Describe the process and decisions required for risk-based earthing system design
• 2.4 Explore a range of methods used to evaluate the performance of earthing systems
• 2.5 Explore the functional requirements of earthing systems
• 2.6 Explore common earthing systems that are applicable to a range of equipment types
• 2.7 Explore specialised earthing systems, included how and when they are applied
• 2.8 Explore a range of methods and processes for testing and maintaining earthing systems
• 2.9 Identify opportunities for earthing system design improvement

• 3.1 Identify and collect inputs required for the earthing design process
• 3.2 Select risk tolerance levels which are appropriate for a given scenario
• 3.3 Select methods for assessment of function and performance which are appropriate for a given scenario
• 3.4 Perform risk assessment tasks to produce accurate and conclusive results
• 3.5 Present options for mitigation of risk through earthing system design

ASSESSMENT

The online course includes 'test your knowledge' quizzes, but there is no formal assessment for this course. Participants will be issued with a certificate of attendance.
