Abstract: | The misjudgment rate of fault feeder selection device is high for existing detectors based on single method.In the paper,fault feeder selection device is put forward on the basis of the mutual integral of transient current method and zero sequence susceptance increment method.The experimental results show that the device can select out the fault feeder quickly and efficiently. |
