Abstract
A monitoring device (10) includes a feature amount storage unit (11) that stores a device feature amount which is a feature amount of each of a plurality of electrical devices installed in a predetermined unit in operation; a measured data acquisition unit (12) that acquires measured data of the predetermined unit which is at least one of a total current consumption, a total power consumption, and a voltage measured in the predetermined unit; a feature amount extraction unit (13) that acquires a measurement feature amount which is the feature amount included in the measured data of the predetermined unit; a correction unit (15) that corrects a first feature amount which is the device feature amount or the measurement feature amount based on unit feature information indicating a feature of the predetermined unit; and a presumption unit (16) that presumes the electrical device being in operation using the corrected first feature amount, and a second feature amount which is the device feature amount or the measurement feature amount, and a different feature amount from the first feature amount.
