Until now,the corona current produced by'Lightning eliminator' and the eliminating principle of the'lightning eliminator'have being unknown question.In this paper, based on the measurement of corona current and electric field produced by 'lightning eliminator', corona current density during recovery of electric field was eval- uated on the theoretical from recovery characteristic of electric field on the ground after the lightning. The results show that even if the electric field reached to stable stage,measured value is an order larger than theoretical value.However, theoretical value is as same order of magnitude as corona current caused by natural point on the ground. The corona current caused by'lightning eliminator'is not stronger than that of the natural point. In addition, the structure of'lightning eliminator'(stronger local sur- face eletric field and bigger corona effective area) can amplify the smaller change of elec- tric field in the air. Therefore,the displacement current was increased. So the function of corona current on eliminating principle is not evident.
