Metrics and Strategies for Design of DC Bias Resilient Transformers
IEEE Open Access Journal of Power and Energy, 2023 Geomagnetic disturbances (GMDs) give rise to geomagnetically induced currents (GICs) on the earth’s surface which find their way into power systems via grounded transformer neutrals. The quasi-dc nature of the GICs results in half-cycle saturation
