| Abstract: | The operation characteristics of fast tripping current protection,adaptive current protection and distance protection are compared. The relay setting values of fast tripping adaptive current protection are determined on line according to condition of power system and fault types, the distance protection can not be affected by condition of power system and fault types. Their operation characters are much better than that of current protection and they will be used more widely in feeder lines. |

| Keywords: | adaptive distance protection fast tripping current operation characteristics |
