About Course

Welcome to Revo Certified basic overhead line asset inspection training course. This online component will be used as an introduction to a 2-day in-person course where we will provide more information, more detailed training, have more discussion, make sure you are comfortable with the content and why we have presented it in this way, and go through practical examples and tests. In-person training course bookings will re-open again once Covid-19 restrictions are lifted!

If you don’t want to do the full training and are only interested in specific modules, please refer to those specific courses. For certification in those specific modules, contact us to discuss options.

We recommend yearly refresher training to maintain certification, and hence the provided certificate is only valid for one year.  

Please note that we can also provide group pricing, client-specific customisation, and training, and we can even build a course that is specific for your utility.

The slide handouts for each module can be downloaded from the first lesson in each module.

SCOPE

This online training covers the basics of condition inspection of overhead power lines, poles, streetlights, monopoles, and their attachments. This is a very practical topic, and we find a greater level of understanding is reached from the in-person training on this topic, but this package is designed to reduce the in-person training time and cost requirements.

It includes work associated with:

  • – Visual condition monitoring of the above-ground portion of the pole, crossarm, conductors, hardware, and equipment attached to determine the integrity of the system.
  • – Sounding techniques,
  • – Residual strength determination,
  • – Criticality assessment.
  • – Completion of inspection and the general requirements for this.
  • – All common pole materials are included

This course is designed to improve significantly on the Australian UETTDREL18 Certificate II course. It focusses on having the students reach a higher level of understanding as to what they are doing and why, and covers a wider range of inspection scenarios.  There is a focus on how and why different defects occur and their criticality to public and worker safety and the ongoing reliability of the network.

We also introduce the full range of traditional and currently available NDT techniques, so the inspectors are aware of the pros and cons of each, which allows them to be more engaged in assessment and use of the techniques.

Why?

We created this course as there are no inspector training courses available that would stand up to expert scrutiny. All the recent court cases pointed fingers at inspectors that were trained in the RTO course in Australia, and we want to help limit these cases by up-skilling the inspector and empowering them. Even with the Australian Cert II being available, we are not seeing a significant take-up. After some investigations, we found this was due to;

  • – Lack of practical content and education as to why certain aspects of inspection are done.
  • – The course has too much safety and treatment focus, which differs between utilities.
  • – The course is centric to the utilities that were the main contributors and not general enough to cover all situations, so most just stuck with their own in-house training, which isn’t overly comprehensive either.
  • – There is a push from safety regulators and outcomes from legal trials that suggest external training by suitably qualified trainers is preferred.
  • – RTO courses don’t have to be presented by people with any experience in the field. This leads to people being signed off and certified by people that are not as experienced as they should be to determine someone’s competency in the inspection process.
  • – The inspectors that are graduating from the programs are not as skilled as would be desirable to get the best value from their services.

We have elected to offer the course as a non-RTO training workshop as it allows us more flexibility to tailor for specific customers, but also to keep up with technology at a much faster rate than what the RTO program offers.

In-Person Training Scope

The in-person training part of this course will cover the following in more detail;

  • – Criticality assessment
  • – Sounding techniques
  • – Diameter measurement, including what to do with lots of obstructions
  • – How to take photos for maximum usefulness to the asset managers
  • – Above ground visual inspection techniques
  • – Typical loads, calculation basics, and how to handle Pi structures, stay poles, pole-and-a-half structures, etc.
  • – Basics of risk assessment
  • – Q&A time to cover any questions that students have that are specific to their utility

It will also involve a practical exam that must be satisfactorily completed to pass the course.
