In this master thesis, the relationship between meteorological conditions and fault data from the electrical distribution grid is analysed. Upper Austria and Styria are chosen as investigated area because of the location - north and south of the Alps - and the available fault data. As a general introduction, the relationships and dependencies of Environment - Technology (Electricity) - Society (Human) are examined closely and their facets are shown. Thereafter, meteorological data (from 1971 to 2011) is analysed and prepared, which were provided day exactly by the ZAMG. Hazard events are filtered out from fault data and analysed in more detail. Various analyses were performed, such as assessing afflicted areas in relation to hazard events in terms of supply and function. The previously prepared data from meteorological conditions and grid faults are therefore superimposed and evaluated together. From these results "Rules of Thumb" are derived. At the end the research questions are answered and the hypotheses are verified. A correlation between meteorological conditions and faults are found. Resilient "Rules of Thumb" cannot be set up, but trends are clearly visible. Furthermore, an outlook on further possible research projects is given.
