Differential protection can be characterised as: O a. Highly discriminative protection, operating without delay which does not provide backup functionality. O b. Fast operating, non-unit type protection, which provides backup functionality. O c. I don't know. O d. Slow operating, unit type protection, with no backup functionality. During phase-to-phase faults the following relations of sequence component currents can be observed: O a. Sequence currents conform to the following relation: 11 > 12 > Io O b. I don't know. O c. The zero sequence current is always zero. O d. The zero sequence current has the highest amplitude, i.e. Io > I2 AIO > 11 Distance protection can be characterised as: O a. I don't know. O b. Fast operating, unit type protection, with no backup. O c. Protection which estimates distance to fault by measuring positive sequence impedance using voltage and current measurements O d. Backup protection which always operates with a delay to ensure correct time discrimination.
