A must-attend course that will benefit all those in the rail industry who have had only a little exposure to earthing & bonding – build your confidence & appreciation of the safety, due diligence & system requirements, design parameters & operational realities.

Key Learning Objectives

  • Illuminate the mislabelled ‘Black Art’ of earthing
  • Discover the science and craft required to make wise decisions regarding earthing system requirements
  • Discuss matters relevant to safety and earthing systems in organisations
  • Appreciate the complex problems of inductive and conductive interrelationships between substation and power line earthing systems and other conductive assets such as tracks, cabling and fencing
  • Recognise a coordinated approach to the design and management of power earthing systems, lightning protection systems and other rail systems
  • Understand inspection and testing as imperative tools in earthing system management
  • Investigate techniques for solving problems found in earthing system design, using both empirical and analytical computer based techniques

About the Course

This course provides participants with a sound basis in science and practical examples for understanding and problem solving with earthing systems in the rail environment.

The course begins with an introduction to the physics of earthing including the areas of circuit fundamentals, conductive effects, proximity, mutual earth resistance and inductive coupling.

It will then cover soil resistivity fundamentals, field testing and model assessment and derivation before moving on to empirical and analytical voltage design methods and analysis issues for typical applications.

The course includes interactive practical sessions where we will ‘see’ how specific changes and errors affect outcomes which is invaluable in turning information into understanding.

Over the course participants will be invited to present real life issues and examples they have wrestled with, which will then be analysed using the understanding and skills developed during the program.

Who Will Benefit

Course pre-requisite: Some understanding of electrical systems is required

This course will benefit:

  • Those requiring an introduction to or an understanding of earthing systems in a rail environment
  • Non-technical people will attain a proper awareness of the issues while electrical engineers and experienced technicians will further benefit from methods for first pass planning and review

Communicated the course information clearly and made it interesting.”
Signal Electrician, ARA Security

Good presenter of information, encouraged discussion, answered questions well, contributed experience and outside industry knowledge.”
Manager Traction Power Maintenance, Queensland Rail

Thorough knowledge and experiences presented well and enthusiastically. Always open to any questions.”
Graduate Overhead Engineer, KBR

Being able to relate actual railway scenarios with someone who understands the railway environment. His enthusiasm and the fact he could answer most things without saying ‘I will have to look into that’ which a lot of presenters do.”
