Nowadays, sectors like trade, mobility, health care or even public policy do highly depend on the power grid. Furthermore, there is a trend to move the electrical energy generation from central power plants towards spread out renewable energies. To manage their fluctuating production, the former demand-based control system has to be replaced by a supply-fitted consumption system. The additional electronics integrated into the power grid potentially raises its susceptibility to intentional electromagnetic interference (IEMI). Initial tests with the Smart Meter device category revealed a high susceptibility to High Power Electromagnetic (HPEM) interferences in the whole tested frequency range. In order to probe components more critical to grid stability, we are expanding our research to a higher hierarchical level – the substation control systems. These critical devices revealed a lower susceptibility than the Smart Meters, but the still occurring failures have a greater impact on the grid. The application of different test methods served the attempt to identify coupling paths into the configuration under test.
