Abstract

A condition analyzing device (10) includes a current acquisition unit (11) that acquires a current signal flowing through a target equipment (30), a parameter calculation unit (12) that is configured to calculate values of a plurality of parameters which change due to a condition of the target equipment and have a correlation between each parameter, on the 5 basis of the current signal at a timing related to a constant period, and a display information generating unit (17) that is configured to generate display information in which a division line representing a predetermined threshold value used as a criteria of a condition for the target equipment, a first graphic representing values of the plurality of parameters related to a certain timing, and a second graphic representing a variation of 10 values of the plurality of parameters calculated at different timings are arranged on a coordinate space by axis corresponding each parameter. 15
