Transient fluctuations in the earth's magnetic field are caused by solar flares or other solar phenomena. These magnetic field disturbances cause quasi-dc geomagnetically-induced currents (GIC) to enter a power system at grounded neutral points. This paper presents the results of studies investigating the effects of GIC upon current transformer (CT) and relay performance. The average CT flux density and CT error are examined in the presence of GIC.
