<p>A system (10) and a process for detecting and controlling ungrounded or inadequately grounded parts (12) prior to subjecting said parts (12) to an electrostatic coating process comprising: a radio-frequency detection system (47) located outside the electrostatic coating area for sensing energy levels radiated by sparking and/or corona discharge resulting from an ungrounded or inadequatelly grounded part (12) under test; and a coincidence detector (49) located within the electrostatic coating area for sensing and discriminating energy levels radiated by spurious sparking and/or corona discharge resulting from an external source other than said ungrounded or inadequately grounded part (12) under test.</p> |
