Magnetic field shielding of cylindrical shield has been studied for a long time, and analytical solution has been derived at power frequency. This paper, based on the previous work, presents an analysis on shielding principles of linear cylindrical shield at power frequency. Shielding principles are developed from simplified shielding formulas under a single-shell & inside-source configuration. Partition of parameter space is introduced, and four regions (linear induced-current, nonlinear induced-current, flux-shunting and induced-current/flux-shunting shielding) are identified geometrically. It reveals inherent relationship between shield parameters and shielding effectiveness. Sensitivity study of shield parameters is conducted too. It discloses inherent patterns of parameter impact on shielding effectiveness. Convenient design curves are presented in the 2D space. These shielding principles and design curves will alleviate design burden in shielding design.
