Abstract:
1. A method of operating a high voltage power supply of an electrostatic precipitator having a collector electrode capturing particulate that is charged by an ionized gas in an electric field created by a high voltage corona discharge electrode energized by a high voltage power supply, said method comprising protecting said power supply from overload when current demand becomes too high due to electrode contamination, said protecting step being selected from the group consisting of: limiting electrical current input to said power supply notwithstanding said increased demand responsive to said electrode contamination; disconnecting electrical current input to said power supply notwithstanding said increased demand responsive to said electrode contamination; and disconnecting the output of said power supply to said corona discharge electrode notwithstanding said increased demand responsive to said electrode contamination.
