Introduction: System Modeling The first step in the control design process is to develop appropriate mathematical models of the system to be controlled. These models may be derived either from physical laws or experimental data. Transformer inrush currents are highmagnitude, harmonicrich currents generated when transformer cores are driven into saturation during energization. These currents have undesirable effects, including potential damage to the transformer, reduced power quality on the system, and relay malfunction.
