ABSTRACT:
A low voltage comparator circuit is utilized for comparing the current flowing into and out of one of the electrodes of a gas discharge device with a preselected value. The comparator provides an output signal to an optical isolation means for generating light waves in response to the comparator means output. The optical isolation means includes a photosensitive means for providing an output signal which is responsive to the intensity of light waves generated by the light generating means. The output of the photosensitive means is electrically connected to an input means for a current control which includes a first terminating means electrically connected to the one electrode of the gas discharge device, and a second terminating means electrically connected to the high voltage supply.
