Sammanfattning
The aim of this master thesis was to lead two projects concerning live high voltage working. It has been proposed by RTE (Réseau de Transport d’Électricité, the French Transmission System Operator). Live high voltage working permits to carry out maintenance works without line or substation bay outage. Because it avoids losses in other lines or costs due to energy not supplied, live working is often worthwhile. In engineering units however, young engineers do not have much knowledge about live working and they ask therefore systematically for an outage when they have a work. To advertise live working, communication tools such as a guide have been elaborated during the thesis. Safety is the principal concern while carrying out live working. Particularly the working distances have to be respected at each moment. Hence work preparations are highly important. In order to visualise the working, drawings are done using a Computer Aided Design software called AutoCAD. Lots of actions have been done in order to make this very complete software easier for operatives who are not designers. They include the library updates, the writing of a graphic charter, the programming of a new library layout, the training specifications and lots of communication. The two projects have common points. At first they did not have precise specifications. As a consequence the chosen solutions are not the good or the bad ones. From an economical point of view, the two projects do not require a huge investment compared to what they could yield. From a technical point of view, both projects are feasible. Finally these projects will be developed in the coming years
