Withstand voltage-testing apparatus.

摘要

A withstand voltage-testing apparatus comprising: a high-voltage generating means (13) for applying a high voltage to a work (11), the withstand voltage of which is to be measured; a ground conductor (12) covering the work (1) with an insulating material; a current transformer (15) around which a conductor (14) connecting the ground conductor (12) and the ground (G) with each other is wound; a variable resistor (19) connected with output terminals 16A and 16B of the current transformer (15); a digital panel meter (17), composing a detector, for detecting a voltage generated by the variable resistor (19); and a warning means (21) for displaying that the work (1) is defective when a voltage detected by the detector is higher than a predetermined value.
