Abstract
Described herein is a method including measuring a current in a wire, normalizing the measured current, and comparing the normalized measured current to a control curve. The control curve is a function of a series of normalized current magnitudes and reaction times for corresponding ones of that series of normalized current magnitudes. The method further includes limiting the current in the wire based upon the comparison. The reaction times for ones of the series of normalized current magnitudes are times at which current limitation would occur if the normalized current remained at an associated normalized current magnitude.
