ABSTRACT:
A capacitor (16) coupled in series with series coupled gas discharge lamps (11 and 12) will effectively block direct current from flowing through the capacitor (16). A detector circuit including a high impedance resistor (17) and transistor (18) provide an alternate path for a small direct current flow, thereby enabling a direct current voltage across the capacitor (16) to be detected. The presence or absence of this direct current voltage provides a reliable indicia of the existence or absence of a gas discharge fault.
