Geomagnetically Induced Currents 2

[Mbrooke]

Does transformer connection make a difference in GIC currents and their mitigation such as delta wye 345kv-69kv vs a typical Wye Grd auto? Also are GSUs effected by GICs such that it needs to be evaluated?

Much thanks. These devices present virtually no impedance during a fault, so MHO elements remain unaffected if not factored in?
