| Abstract: | This paper analysis theoretically the influence of the gap disruptive flashover of insulated groundwire on distance relay, and performance of several usual earth fault distance protections have been extensively tested by using ATP.The results of simulation studies indicate that setting of earth fault distance protection on sectionalized groundwire with gap should be calculated on all the gaps disruptive flashover. |

| Keywords: | insulated groundwire gap disruptive flashover earth fault distance protection |
