A Theoretical Analysis for Finite-Length Electromagnetic Shields of Superconducting Turbine Generators

A lumped parameter circuit representations of finite length solid electromagnetic shields of superconducting turbine generators is developed. A three-dimensional magnetic field analysis is used to calculate the parameters of this representation. The shield lengths are freely chosen which increases the inherent accuracy and usefulness of the representation relative to previous approaches.. The analysis provides the basis for three-dimensional shield design
