Abstract
In a device having capacitive loads in which a plurality of capacitive loads are connected in parallel, power is supplied from an AC power source to a load group comprising the plurality of capacitive loads, the load group is divided into a plurality of small load groups, and 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 a current detecting signal which is detected by the current detecting sensor are equipped.
