Calculation of Magnetic Shielding Effectiveness of Current Comparator
Ren Shi · Jiliang xuebao · 2003
All kinds of heavy current comparators possess the notable perfermance of low drift,high accuracy, and linearity. An important design technique is the magnetic shielding. Although the estimation of magnetic shielding effectiveness was described, the more effective analysis and calculation are needed in industry and laboratory.A new numerical method used to calculate the magnetic shielding effectiveness of comparator is given and the magnetic shielding effectiveness of comparator is analyzed. The FEM mathematical model,and calculated results are given.
