Summary
The new arrangements and constructions of high voltage towers require newly developed working methods, as well. These techniques may improve the use of live-line maintenance in the high voltage transmission system. In Hungary new double circuit power lines had been built and the older towers are fitted with new types of composite insulators. This means new challenges to TSO during the use of live work. One problem is the reduced distances between the different potentials, another is the new arrangement where the use of conductor cars and the different kinds of mounting chairs – made of conductor material – is more complicated. A good example is the lifting of these equipment to the upper phases, when the electrical distances can be shunted; the possibility of the occurrence of a sparkover increases this way. In the High Voltage Laboratory of the Budapest University of Technology and Economics research and development is currently being done regarding to high voltage LLM practice. Within the framework of this work a new technology of insulator string change is to be developed with the use of innovative equipment and a new type of conductor car made of totally insulated materials; these results are introduced in this paper.
