Nowadays the world needs more and more energy and the new requirements are not easily accomplished. It is important for the power companies to always provide consumers with energy on a stable and constant basis. However, this would be impossible if maintenance and repair work required continuous shutdowns to be applied to the network. This will result in a significant loss of revenue as well as user satisfaction and trust towards the power supplier. One of the possible solutions to these problems is the live working. Thanks to this method, you can work on a network without having to disconnect it, so the service level will remain constant.

The quality of services is regulated by the index numbers of Magyar Energetikai és Közmű-szabályozási Hivatal (Hungarian Energy and Utilities Regulator, abbrv.: MEKH). It is the basic and well-thought interest of electricians to keep these indicators low, as this is how the quality of their work is rated. The thesis presents the calculation of two index numbers. One of them is the MEKH 1 index number, which shows us the number of consumer failures, while the other is the MEKH 2 indicator, which examines the time of the cutbacks.

Obviously, with the help of the live working technology, the values of these index numbers improve, because the more work is done with live working, the fewer the number of consumer failures is. The thesis aims to show how the index numbers would change, if some, typically live working works would be performed with potential free works. In this case, of course, the number of consumer failures and the time of outages would increase, hence the values of the indicators would deteriorate, as opposed to live working technology, whereby the values of the indicators can be kept low.
