Analysis and calculation of magnetic shielding effectiveness for comparators
Shiyan Ren, Hengchun Ding, Mingming Li · 2002
A method of analyzing and calculating magnetic shielding effectiveness of comparators by means of long rectangular shell model with a magnetic core is developed. The calculation formula is derived. The error between testing results and calculation data for the magnetic shielding effectiveness of 25,000-ampere dc comparator is less than 5 percent.>
