Abstract
PURPOSE: To detect a section of fault in the transmission and distribution lines, by such means that on condition of the breaker being disconnected by a fault, a time difference be used between the time of automatic closing made thereafter and the time of disconnection made again by a fault.
CONSTITUTION: After a breaker 6 is automatically closed by a reclosing device, a sectional switch 11 will be successively made closing in order at every interval of constant time. A state signal of said breaker 6 is inputted to a remote electric station side transmitter 5 through a coupling wire 8, further transmitted to a control station side transmitter 2 through a transmission line 4, being inputted to a controller 12 through a coupling wire 17. Said controller 12 will make a comparison between the content of breaker state signal, inputted at this time, and the content of breaker state signal, inputted at the time before, to decide, if a change of the state is present, what the cause of change is. At this time, if for an automatic state change in the remote electric station, a discrimination will be made for the state change whether from open to close or from close to open, with a processing operated by the content of memory device 14.
