Abstract
A load estimating device measures a voltage and a current supplied to a plurality of loads connected with a power supply, and obtains feature amounts of the plurality of loads from measurement values of the voltage and the current. A storage device stores a feature amount of each combination of two or more loads in advance. The load estimating device estimates what the plurality of loads connected with the power supply device are, on the basis of the obtained feature amounts and the feature amounts stored in the storage device. The feature amount includes a combination of an apparent power and a power factor.
