Designs of inductive fault current limiters (FCLs) implement conducting or superconducting DC coils to saturate the magnetic cores during nominal grid performance. These coils, however, add significantly to the operational cost of the system, consuming energy and requiring maintenance. A derivative of the inductive FCL is a design implementing permanent magnets as an alternative to the DC coils, eliminating practically all maintenance due to its entirely passive components. In this project, we describe a design based on permanent magnets as a source of biasing the cores, implementing a unique configuration that utilizes a closed magnetic path, eliminating multidirectional flux within the cores. We show here how this proves to be an advantage, significantly increasing the device's efficiency in terms of limiting capability to total device volume.
