Effect of Capacitance on Electrostatic Precipitator Operating Voltage

Pilot plant precipitators can usually operate at much higher voltages than the equipment they are meant to simulate. A possible reason for the difference in the sparkover voltage is the difference in the capacitance of the electrode systems. Experiments are carried out with apparatus which simulates the events leading to sparkover in an electrostatic precipitator. Curves of the relationship between sparkover voltage and capacitance are shown.
