Abstract [en]

In this thesis, the conditions of using the maintenance method live work at the Swedish TSO, Svenska Kraftnät has been analyzed. The study is limited to only include live work on 220 and 400 kV. The live work method is a type of maintenance that can be done, on lines or stations, even though they are still energized. The purpose of this thesis has been to map the present live work situation at these levels in Sweden. The study is based mostly on interviews with people who have specific field competence with in live work but also with personnel at Svenska Kraftnät. Besides the study of Swedish usage of the method, a study of other countries was made.

Live work isn’t new in Sweden, the method was first used here in the 1950’s. The method partially came back in the 1970’s, but it wasn’t until 1997 that the method was fully permitted in Sweden. Before 1997 government permission was mandatory to have to be allowed to use live work. This rule was changed in 1997 and now the method is equally valued to the other methods. This study also shows that there are incentives for using more live work in

Sweden, especially now when the country has been split into four different electricity markets. But there are several obstacles for a development in live work usage. If Svenska Kraftnät wants to increase their live work usage there are many actions that have to be made. In the end of this study these actions are presented.
