Abstract:
1. An electrical tester for testing the high tension in a high tension circuit, having a predetermined high tension voltage parameter and comprising: first and second contacts disposed in a fixed spaced apart relationship with one another, and being connectable to said high tension circuit; a first electrode connected to one contact; a second electrode connected to the second contact, the first and second electrodes being spaced apart from one another by an air gap and defining a predetermined width, wherein a resistance is preset to a resistance corresponding to the voltage in said high tension circuit to be tested; and a signal device responsive to high tension discharge across said air gap to generate a signal, whereby when said predetermined high tension voltage is applied to said first and second contacts, a spark will jump the gap between said first and second electrodes, thereby activating said signal device, and when a high tension voltage is applied which is less than said predetermined high tension voltage no spark will jump the gap, and no signal will be generated.
