Point on Voltage Wave Switching for Sympathetic Inrush Current Reduction

The present work has the purpose of eliminating these transient inrush currents. So this paper presents a data acquisition system based on dSPACE board 1104, and a laboratory setup experiment to measure the sympathetic inrush current. Moreover, a control switching to mitigate the sympathetic inrush current in a 2 kVA transformer will be developed and applied experimentally in the laboratory and also in the simulations. This control strategy is performed by considering the residual flux at the opening instant of related circuit-breaker. A comparative study is carried out showing the validity of the mitigation technique.
