Abstract

1513038 Electric protective systems GENERAL ELECTRIC CO LTD 1 Oct 1976 [10 Oct 1975] 41625/75 Heading H2K Magnetic saturation of the core of an electrical transformer (e.g. a current transformer) is detected by applying to a winding thereof a signal of higher frequency than the intended transformation frequency and detecting whether the impedance of the winding falls.
