Abstract: | In this paper the development of a tool for a fast and simple evaluation of the technical condition of electrical networks will be presented. With this tool it is possible to compare different networks and network sections of different power suppliers as well as utilities of the same voltage level or network sections of the same utilities. Whole networks, but also individual components such as transformers and switchgears can be evaluated. An exact condition evaluation of networks represents a disproportionately large expenditure of time. To get a fast overview over the technical condition of networks and electrical components the knowledge of experts is necessary. The presented method takes into consideration both: expert knowledge as well as the consideration of age, maintenance and operating loads of networks and their components. These aspects are included in reliability computation mathematical functions which will be used in the developed technical condition evaluation tool. Beside the evaluation of the technical condition the tool is based on the maintenance expenditure and the priority of the examined networks, too. |
