Although the performance of this type of protection is quite satisfactory in most respects, some concerns remain about its tendency of ‘false’ tripping on magnetizing inrush currents [1], [2], [3]. Such currents could not only reach ten times the magnitude of the transformer nominal current...
Geomagnetically induced current (GIC) results in the part-cycle saturation of the transformer core and contributes to a considerable increase of the harmonic components in the transformer currents. Under such conditions, transformer differential protection is expected to be blocked from operation, failing...
