In China,most of distribution system is neutral noneffectively grounded. And the single-phase fault often happens through cement pole. In this paper,firstly,the voltage of the fault phase and the current of cement pole are derived in 10kV neutral noneffectively grounded distribution systems when cement pole has single-phase ground fault.Secondly,the online fault location method is proposed based on voltage gradient of cement pole.Thirdly,the resistence characristic of cement pole is analyzed and the distance obtained from the gradient voltage of cement pole is given.Finally, the theoretical analysis and simulation experiments show that the method is feasible.
