  fault arc
In the algorithm development, the fault arc is included in the complete fault model.
      
As it is known, the fault arc resistance can be calculated by the Warrington formula.
      


Experiment method is used to study the characteristics of fault arc. Some features of zero zone arc voltage are obtained. A new algorithm for faultlocation in power transmission lines is described in this paper. The algorithm requires only the data from one terminal and can exclude the influence of faultresistance and itsequivalent inductance, load current and system operationcondition on two sides. Computer simulation is alsopresented.
