  • Method of and system for disconnecting faulty distribution line section from power distribution line
    Patent number: 5341268
    Abstract: A main controller installed in a distribution substation of an electric power system sends a request signal to each of section controllers installed in individual section switches upon detecting a distribution line fault. Each of the section controllers performs fault detection individually. Each section controller judges whether its associated section switch is dividing the distribution line between faulty and normal line sections on the basis of fault detect signals from the other section controllers. If it is judged that its associated section switch is dividing the distribution line between faulty and normal line sections, that section controller opens its associated section switch.
