Geomagnetic Disturbance Survivability: Why Distribution-Class Solid-State Transformers Are Likely Less GIC-Vulnerable Than Iron-Core Equivalents
· Power Electronics
4 sources GICs are quasi-DC currents in grounded power-system portions from geomagnetic disturbances (solar storms). Iron-core transformer GIC vulnerability: core saturation → reactive power absorption + harmonics + hot-spot heating…
