“…Where r1 and r2 are the inner radius of the shell and the outer radius of the inner conductor； r δ Is the relative dielectric constant of SF6 gas, usually taken as 1.In actual GIS, in order to have high current density, generally 2 1 r e r = ,Therefore, the conductor wave impedance is 60 ~ 100Ωand 75Ωin this paper. Due to the relative dielectric constant of SF6 gas 1 r δ ≡ , it is generally believed that its wave speed is equal to the speed of light.…”

Lightning impulse overvoltage is the main factor to determine the insulation level of substation, and the insulation coordination between the insulation level of the protected electrical equipment and the arrester of the protection device is the most basic and important insulation coordination in the power system. In this paper, the working principle, characteristics and lightning current simulation of zinc oxide arrester are described. Then, taking a 420kV gis substation as an object, an electromagnetic transient simulation platform is built by using electromagnetic transient program (EMTP-ATP), which is used to simulate 420kV When the 400 kV side of GIS Substation is struck out of the line tower by lightning, the insulator flashover occurs, and then it invades the substation along the transmission line to generate Lightning Overvoltage on the equipment. Considering the operation mode of single line single bus single transformer with the most serious overvoltage, the overvoltage waveform of the voltage transformer at the outlet end and the main transformer port of the 420kV GIS Substation is obtained under the given arrester configuration scheme. Through calculation and analysis, the design meets the requirements of specifications and engineering practice.

Everyday experience and scientific observations, including those made as far back as the 18th century, indicate that lightning most often strikes individual structures elevated above the earth, these may high voltage substations. The lightning conductors as a means of protection from direct lightning strokes were used much before the beginning of the present era, but they acquired wide recognition only in the middle of 18th century as a result of the work of Benjamin Franklin. The paper presents an approach to teaching high voltage course using specially designed exercises that can be done using MATLAB. This paper present MATLAB based software to design substation lightning protection. Evaluation of the simulation with 40 students is very positive in terms of their developing confidence in and understanding of this simulation. ß
