This study aims to find new critical distances for transformer re-energization during network restoration after a blackout. Energizing a power transformer, in a grid that is lightly loaded due to the restoration process, involves a risk of temporary harmonic overvoltage. The overvoltages can, if they exceed a certain limit for a certain time, be harmful for the components of the grid. The rule which already exists at RTE states that there is need of a simulation study if the distance between the transformer to be energized and the closest load exceeds a certain length, depending on the transformer type. However, the critical distances already used are not satisfying, because in most cases the overvoltages are far from being dangerous, even ...
