Abstract
A method of and an apparatus for testing a withstand-voltage of a work having a core conductor coated for insulation with an insulating member, the method comprising the steps of: enclosing the insulating member by a grounded conductor; providing first and second discharge electrodes for the core conductor and the grounded conductor, respectively so as to connect the first and second discharge electrodes between the core conductor and the grounded conductor; applying high-voltage pulses to the core conductor so as to detect discharge beams generated in a gap between the first and second discharge electrodes; and judging whether or not the insulating member has a proper withstand-voltage.
