| Abstract: | For a three-phase and two-phase short circuited fault on the protected line, the protections may have unwarranted trip or failure to trip known by analyzing the performances of directional impedance relay and full impedance relay while there are short circuited faults and secondary circuit of PT is broken. |

| Keywords: | line breaking failure to trip unwarranted trip impedance relay |
