摘要：
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.
摘要（中）：
一种系统（10）和用于在对所述部件（12）进行静电涂覆处理之前检测和控制未接地或未充分接地的部件（12）的方法，包括：位于静电涂覆区域外部的射频检测系统（47） 用于感测由未测试的未接地或不充分的接地部件（12）引起的火花和/或电晕放电辐射的能量水平; 以及位于静电涂覆区域内的重合检测器（49），用于感测和鉴别由除了所测试的所述未接地或未充分接地的部分（12）之外的外部源产生的由假火花和/或电晕放电辐射的能级。
