Abstract
The formulation of calculation method for electromagnetic inducing current by aerial power distribution line is established. Nearby telecommunication cables can be induced due to the leakage of neutral current because the neutral line of power distribution is grounded at every 50 m distance. By the existing calculation method, the neutral line is regarded as a shielding conductor and the neutral current roles as an inducing current. So the error range to real measurement value is largely extended because the changing effect of leakage current flowing in the ground is not reflected. The leakage current returns to the power substation through the ground and is cumulated as being closer to the substation. When this practical inducing mechanism is applied, the deviation rate of calculation can be drastically reduced within about 100 % range compared to 1000 % of the exsiting method.
