| Abstract: | The shielding theory of power frequency magnetic field is described; and shielding techniques of magnetic field from indoor distribution substation busbars are discussed. Using the 2D eddy current finite element method, the effects of installation method, material and dimension of shielding board, etc. on shielding efficiency are calculated and analyzed. Finally, some suggestions are put forward for engineering practice. |
