A first sum of a first high voltage and a first low voltage related to a first sensor is determined, where the first sensor is further related to an excitation voltage. A second sum of a second high voltage and a second low voltage related to a second sensor is determined, where the second sensor is further related to the excitation voltage. The excitation voltage is provided to both the first and second sensors using excitation wiring. A determination is made whether each of the first sum and the second sum changes beyond a threshold amount during a first time interval. After determining that each of the first sum and the second sum has changed beyond the threshold amount during the first time interval, an indication of a fault in the excitation wiring is provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Linear variable differential transformer (LVDT) excitation wiring intermittent failure monitor","description":"Methods and apparatus are provided for detecting faults in excitation wiring.
