Abstract
A high voltage monitor and display for electrostatic precipitators producing a digital output code representing the magnitude of the high voltage associated with the ionizer and collecting cells which is applied to a series of display elements arranged in a spaced linear relationship such that the number of adjacent display elements illuminated corresponds to the magnitude of the high voltage to provide a visible indication of ionizer cell and collector cell performance. A predetermined minimum cell voltage is established digitally, and the high voltage power supply inhibited when the high voltage falls below the predetermined value. Alarm means are also provided for indicating when the collector cell or ionizer cell voltage is below the predetermined operating minimum.
