Australian electricity distribution companies are using Virtual Reality (VR) technology for internal training. According to the article, the technology was used for the "Safe Approach Distances" training, a module to train workers on working with live electric assets. The VR program simulates the inside of a zone substation or a scenario that would see two workers working on overhead power lines in 3D which gives people a safe, realistic space to learn.
There is no mention of the costs involved for the training. According to this 2018 CNBC article, VR training can be substantially cheaper as compared to conventional training because it does not involve costs such as booking training rooms and assigning specialized instructors to the task. I am assuming that there must be the added benefit of saving on time in this case because there are no site visits.
But the post does not mention costs involved in developing specialized training modules for an industry. For example, the training program mentioned above is mandated by the Victorian Electricity Supply Industry (VESI) and it must have to meet certain criteria for compliance. I also wonder whether the absence of a live (and unpredictable) training environment is a drawback in this case.
