High impedance faults are detected based on fault current measured by fault detection devices but an important fault is the downed or broken power line fault not touching the ground cannot be detected when there is not enough faults current to operate fault detection devices in over head power distribution. Many methods to find high impedance faults exist. However, no proper method exists to find the downed or broken power line fault not touching the ground .Such a condition represents no electrical abnormality and till now its detection would probably have to depend on visual sighting. This is a major safety concern for the public. At present there are no electrical techniques to detect this fault with 100% accuracy with less cost. This study proposes detection of downed or broken power line fault not touching the ground by F-PLCCG. The proposed method is applied to 3-phase system/single phase system and finds the fault in sec.
