Device having capacitive loads and abnormality detecting method thereof

A device having capacitive loads in which a plurality of capacitive loads are connected in parallel, a current is supplied from an AC power source to a load group comprising the plurality of capacitive loads,

• wherein the load group is divided into a plurality of small load groups, and further including:
• a current detecting sensor for detecting a current which flows in at least one small load group at a side which is closer to the load side than a branch point at which the load group is divided into the plurality of small load groups, and
• a current abnormality detecting part for determining an abnormality of a load by detecting a rush current which flows between the plurality of small load groups and flows into a load which is shorted in a case where any of the capacitive loads is shorted during operation of the device having capacitive loads.
