Abstract The difficult point of the high impedance fault(HIF) detection method is how to ensure its model accuracy. In order to solve this problem, this paper defines the characteristics and properties of HIF .Then aiming at the insufficient of the traditional Emanuel model and arc model, based on the measured data and physical phenomena and numerical calculation method, this paper establishes a new model. The model of simulation is simple and fast and the parameters are easy to adjust. Under the environment of EMTP simulation, the results show that the characteristic of HIF is obvious and then this paper analyzes the model error sources.

Key words： High impedance fault Numerical calculation method HIF model EMTP simulation
