Abstract
Embodiments of the invention include systems and techniques for implementing voltage differential transducer (VDT) fault detection. Embodiments include a computing resource electrically coupled to an AC power supply, a VDT including a primary winding and a set of secondary windings, wherein the VDT is electrically coupled to the AC power supply. Embodiments also include a current sensing circuit electrically coupled to the AC power supply and the VDT, and a signal processor electrically coupled to an output of the VDT and the computing resource, the signal processor providing a signal indicative of a voltage differential of the set of secondary windings of the VDT, that is used by the computing resource to make an error determination.
