Abstract

PURPOSE:To permit the quantitative measurement of leak condition without resting on the sense of workers. CONSTITUTION:The leak condition detector I consists of the high-voltage generation circuit 1 by which to generate DC high-voltage and to apply it to the high-voltage cable 2, the detection circuit 3 by which to detect leak signal at the time when high-voltage output from the circuit 2 is converted into working voltage level by voltage dividing circuit, its maximum value is kept by peak holding circuit through inversion amplifying circuit, and high-voltage is applied distributionally to the whole of high-voltage circuit portion, the decision circuit 4 by which to compared the output of the circuit 3 with an optionally settable decision level, and the displacy circuit 5 by which to indicate the decision result of the circuit 4. Thus, it is possible to detect the leak condition at the time when high voltage is applied distributionally to the whole of high-voltage circuit from the outside during the downtime of engine.
