A approach of distinguishing between temporary and permanent fault in single pole autoreclosing based on fault location is proposed. This criterion uses the fault location result to get the fault point voltage and takes the fault point voltage in theory as the setting value to distinguish the permanent fault from temporary fault. When the fault voltage is less than the setting value, the fault is permanent. Otherwise, a temporary fault is proved. Also resolutions have been discussed in high impedance and how to get the line-side voltage when no line-side voltage transformers have been installed. A lot of simulations show that it can identify the temporary and permanent faults correctly and be easily applied in a practical system such as 110 kV-220 kV transmission lines and 330 kV-500 kV transmission lines without shunt reactors.
