| dc.description.resumo | The geomagnetic induced currents (GICs) are currents that occur due to movement of ionized particles in the earth´s magnetic field. The solar flares cause the discharge of ionized particles in the space, wherein a portion of these charges are ajected toward the Earth, modifying the magnetic field inducing current mirror surface. The GICs have the feature very low frequency, almost continuous, with average amplitude ranging between 0 and 15 but are peaks that can reach 100 A. The duration of the current ranges between a few milliseconds to a few minutes. For a long time electrical engineers believed that GICs were problems only electrical systems at high latitudes. However, in recent years it is speculated that the causes are for various shutdowns unscheduled in Brazil this is due to an anomaly in the South Atlantic. Given this situation this study aims to verify the impact of GICs on current transformers (CTs). The circuit was implemented in software EMTP-ATP, from the simulation it was observed that the CT saturates faster for low frequency GICs. | por |
