Abstract
A system for protecting an electrical component, drawing current from a power source, utilizes a sensor providing an output signal proportional to the square of the load component current. The squared-current signal, when greater than a squared-normal-current signal, is integrated and compared to a current squared-time value. A system output is enabled if the load component instantaneous i.sup.2 t value is greater than the current squared-time value set at the comparator, to remove the current flow to the protected component.
