    摘要： This disclosure describes an apparatus for detecting impending saturation in magnetic cores. A saturable core, which may be toroidally formed, has an aperture in the circumference of the toroid. Windings are separately wound around the toroid between the aperture and the outer edge of the toroid and between the aperture and the inner edge of the toroid. The windings are serially connected in voltage-opposing relation. When saturation of the core starts to occur in one direction or the other, a voltage unbalance in the windings occurs. This unbalance causes a signal to occur which is detectable and indicates the start of saturation.
