摘要：A current sensor (23) for detecting a full return current is connected to a highvoltage generator (14). Further, a leakage current detector (24) including current sensors(25 to 29) for detecting a leakage current is provided at the surface of the cover of acoating machine (1), air passages (4, 7, 12) and a paint passage (9). And based on currentdetection values (It, Ia to Ie) obtained by the current sensors (23, 25 to 29), a high voltagecontrol unit (20) controls a power supply voltage control unit (15) and a high voltage tobe output from the high voltage generator (14) can be raised or dropped. Therefore, byemploying the current detection values (It, Ia to Ie), the high voltage control unit (20) canidentify and provide a notification of a location whereat the leakage current is increasedand the insulation is deteriorated, and can request an operator to perform maintenancefor the pertinent location. Furthermore, upon the occurrence of an abnormality wherebythe insulation is deteriorated, the high voltage control unit (20) can stop the supply of ahigh voltage.
