Dual Formulation Approaches for Low Voltage Reactors Taking Affects of Air Gap into Account

A low-voltage reactor (LVR) is an important electric equipment used in low-voltage electrical systems to stabilize current and protect electrical devices from potential disturbances or voltage fluctuations. Thus, it plays a crucial role in maintaining stability and safety in electrical systems. In addition, the LVR also assists in protecting electrical devices from external factors such as a noise interference, short circuits, or creating stable conditions for device operations. Thus, the study of electromagnetic parameters of the LVR is really very important and necessary for researchers and manufacturers. In this research, a dual-formulation technique is proposed to compute and evaluate magnetic field distributions, fringing and leakage fluxes, eddy currents, and energy density) of the LVR. The developed technique also permits to investigate the effects of the air gap thickness to electromagnetic parameters of the LVR.
