Abstract
Fast transient analysis of a passive fault current limiter (FCL) using permanent magnets can be done by direct numerical solution of a singl e non-linear differential equation, The non-linear B-H excursion that is caused by hysteresis is incorporated in the computation using a tra nsient hysteresis model. Rational fractions are used to represent the parent hysteresis loop curves. Since the method uses preconstructed ex pressions as applicable to FCL schemes only, computation time required is less.
