Abstract

DocketNo. PMAA--US,CN,SG,MY,ID,TH, Status: FINAL 42 A phase group estimation device (10) according to the present invention includes: a data acquirer (11) that acquires data transmitted from a smart meter; a storage (15) that stores equipment information indicating a 5 correspondence between the smart meter and a pole-mounted transformer corresponding to the smart meter; and a phase group estimator (13) that classifies processing sections into phase groups based on the equipment information and the data. Each of the processing sections is a section 10 corresponding to a pole-mounted transformer, and each of the phase groups is powered by the same phase of a distribution line.
