Analysis of Pulsed DC ionizer measurement procedures with a CPM Using ESDA RP 3.11-2006

The purpose of this research was to model the Pulsed DC ionizer with a Charge Plate Monitor (CPM) and to compare the results with the actual performance of a CPM measuring a Pulsed DC ionizer. The motivation for the study was that measurement of ionizers using a CPM as defined by ESDA RP3.11 - 2006 produce results which seem to vary dramatically. In a previous study [1]. it was shown that corona ionizers exhibit drift caused by movement of conducting objects in proximity to the ionizer. The most dramatic conductor is the operator himself. Having taken that effect into account, the CPM measurement continues to show large fluctuations in measuring swing and balance voltage as defined by the R.
