Abstract
This study performs a transient analysis of a magnetic current limiter, considering the effect of nonlinearity and eddy currents. The magnetic current limiter is a passive device consisting of magnetic core and permanent magnet. The cores of the limiter typically operate under saturation in normal operation, and come out of saturation at overcurrent or fault operation in the alternate half cycle, causing the entire system to enter a transient state. A general formulation is (required for the performance analysis of the current limiter under steady state as well as transient condition.
