The method involves applying test high voltage by a high voltage generator to a running cable over an electrode (20), and determining breakdowns by detector and displaying the breakdowns by an error counter. The test high voltage is grounded for testing reliability of detection of flaw in a predetermined height, duration and frequency at fixed spark gap. The grounded test high voltage is generated from a high voltage generator of a continuous voltage tester. A controller is integrated in the high voltage generator for controlling a clock according to a program. An independent claim is also included for a flow path voltage detector including a controller. |
