20. Resonant overvoltages caused by transformer energization and saturation : Two EMT case studies conducted using models of the grid in Stockholm and an off-shore wind farm
University essay from Uppsala universitet/ElektricitetsläraAbstract : This thesis investigates the impact of resonant overvoltages and their origin. Series and parallel resonances are present in any electrical grid. The frequency of which this resonance occurs is called resonance frequency. READ MORE
