This objective of this research study is "Design and implementation of a prototype of lenses with augmented reality that instructs new staff to perform the maintenance of electric tables in distribution substations of the interior type". This prototype of lenses with augmented reality was designed and printed in 3D, programmed the electronic devices, and projected in real time the indications to carry out the maintenance and the different electrical quantities of the multimeter through Bluetooth signal, in an efficient way. The population was composed of six electrical technicians, taking as a sample the total population, through non-probabilistic sampling, which were the prototype tests during their activities, subsequently responding to the surveys that resulted in satisfaction at 93.72%. The study concludes that it is possible to implement technological tools in Occupational Health an...
