Abstract: An estimating device includes a storage unit that stores in association with each other state history information showing, as a history, a state of electrical equipment in which an abnormality has occurred, and cause history information showing, as a history, a cause of the abnormality, an acquisition unit that acquires state information indicating the state of the electrical equipment in which the abnormality has occurred, a detection unit that detects, from among a plurality of the state history information stored in the storage unit, at least one of the state history information that is similar to the state information acquired by the acquisition unit, and a notification unit that issues a notification concerning the cause of the abnormality, on the basis of the cause history information that is associated with the state history information detected by the detection unit.

Abstract: An abnormal temperature detection system that detects an abnormal temperature in a cable used to transmit power to a electrical device. The abnormal temperature detection system includes first and second conductors that are disposed along a longitudinal axis direction of the cable, and a plurality of temperature-responsive electronic components that are disposed along the longitudinal axis direction of the cable and are electrically connected to the first and second conductors. The first and second conductors and the plurality of temperature-responsive electronic components form an electrical circuit. An abnormal temperature is detected on the basis of an electrical signal acquired from the electrical circuit.
