Signal: Blocked by Harmonic:5
H2,H4,H5 Blo
Signal: Blocked by Harmonics (Inhibit)
Slope Blo
Signal: Differential protection was blocked by current transformer
saturation. The tripping characteristic was lifted because of current
transformer saturation.
Transient
Signal: Temporary stabilization of the differential protection afterwards the
transformer is being engergized.
Restraining
Signal: Restraining of the differential protection by means of rising the
tripping curve.
