Live working (LW) as a tool for preventive maintenance of electrical installations has a hundred year tradition in the world and more than half a century in Europe. In the last decade, LW has been implemented actively at low voltage in the Slovenian electrical distribution, transmission and generation of electricity as well as in industry and institutions (such as health). Slovenian electrical distribution began with the introduction of LW at low voltage in 2010. Depending on the complexity of the implementation processes, several special studies which define organizational activities, working documents, prescribe the necessary tools and personal protective equipment are being made. Likewise, a specific training program is defined, as well as the required number of workers and instructors, and analysis of the effects of LW at low voltage. The purpose of this paper is to examine whether we can achieve compliance with the requirements for the safety and health, the quality and the effectiveness, and efficiency of maintenance processes with the implementation of LW at low voltage. It is evident from the survey results that safety and health was highlighted as the most important field from the perspective of workers and instructors. It can be summarized that the results of this study demonstrate that workers and instructors in all of the surveyed distributions are aware of positive effects of the introduction and implementation of LW at low voltage. Based on the results and discussions, guidelines for the implementation of the LW at low voltage are given in this study. Given the fact that workers and instructors highlighted safety and health at work we suggest that regular supervision procedures continues within the implementation of individual work orders, and that possible hazard situations have to be assessed at two year cycles of verifying workers and instructors competences.
