| Abstract: | With the effect of line structure, interference source and geologic distribution, the zero sequence impedance of the 500kV transmission line varies greatly. This paper analyzes the zero sequence impedance of several 500kV transmission lines and analyzes the theory and methods of measurement in detail. Meanwhile, it puts forward some problems that should be paid attention to during the process of measurement and calculation. |
