Abstract
A storage unit is configured to store a drive electric current of a submersible pump detected by an electric current detection unit. An identification unit is configured to calculate at least one electric current parameter of a plurality of electric current parameter based on the temporal change of the drive electric current and identify an operation state indicating whether there is an abnormality in the submersible pump and a type of an abnormal operation, based on the electric current parameter.
