摘要：
A fault detection device comprises: a measurement data acquirer that acquires measurement data for current flowing on power supply lines that are connected to multiple electrical devices; a clusterer that classifies the measurement data for a past fixed period into multiple clusters based on at least one of frequency and phase with respect to an AC cycle; a pattern analyzer that analyzes each of the clusters for an appearance pattern of measurement data that satisfy a preset standard; and a fault determiner that determines the occurrence of a fault when measurement data is acquired that differs from the analyzed appearance pattern.
