Detector detects a status change of any of electrical devices based on measurement data of a current flowing in a distribution line supplies power to the devices. Calculator calculates a current waveform change and a power change associated with the status change based on the measurement data. Estimator estimates a candidate originating from the status change based on the current waveform change. Specifying unit specifies a device caused the status change and a type of the status change based on the power change and an estimation result of the candidate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Status estimation apparatus, status estimation method","description":"According to an embodiment, a status estimation apparatus includes detector, calculator, estimator and specifying unit.
