Substations have a large number of signal transmission cables beneath the *** the insulation safety and signal reliability of the cables are affected severely by the electromagnetic *** high-amplitude impulsive currents,the dispersion of currents can cause soil discharge and thus cause unexpected distortions in an electromagnetic *** paper focuses on the distortions of the electric *** general,soil discharge channels occur in the vicinity of the independent *** development of the channel might enhance the electric field distribution and the potential surrounding the outer insulation of the cables(*** surface potential on the cable).Therefore,this paper establishes a platform for observing the soil discharge channel and measuring the surface *** characteristic of the channel is extracted from the captured image of soil discharge channels and the surface potential is obtained by the measured coupling capacitive current on the shield *** paper also presents an improved model considering a dynamic growing discharge channel for the transient analysis of the grounding *** results show the surface potential increases as the discharge channel approaches the *** quantify this enhancement effect,the ratio of the highest to the lowest value of surface potential in different directions is taken as the multiple of the surface potential *** calculated multiples of the surface potential increase are in the range of 1 to 1.64 times under different conditions by the improved ***,taking the soil discharge channel into account is helpful to accurately analyze the impulsive interference of buried cables.
