Abstract: An apparatus for detecting saturation periods of an electrical transformer in which successive derivative samples of the current flowing in the transformer are compared when the current traverses a zero datum, the signs of the respective derivative samples are also detected, and a logical circuit controlled by the derivative samples as well as their signs functions to produce logic signals of one state or another, i.e., 1 or 0 depending upon whether or not the transformer is saturated.
