Multiple failures of transmission lines caused by climatic/atmospheric impact plague many electric power systems. Direct damage from such failures is quite huge, yet it is marginal compared with the social damage caused by the reduction in the supply of electricity. As it is not economical to construct weatherproof transmission lines, preventive actions should be employed the most effective restoration, or to reduce restoration time. A working group of CIGRÉ (WG B2 13) has prepared emergency guidelines based on the experience of large-scale disruptions. Our experience with multiple transmission line failure, as well as the importance of our power grid, lead to the conclusion that it would be wise for HEP OPS to begin with an appropriate organisation of preventive actions in agreement with HERA. To a lesser extent, this also applies to 400 kV buses.
