ABSTRACT:
A withstand voltage-testing apparatus includes a high voltage generator for applying a high voltage to a work, the withstand voltage of which is to be measured. A ground conductor covers the work with an insulating material. A conductor is wound around a current transformer to connect the ground conductor and the ground. A variable resistor is connected with the output terminals of the current transformer. A digital panel meter, which includes a detector, detects a voltage generated by the variable resistor. A warning mechanism displays that work produced by the above is defective when a voltage detected by the detector is higher than a predetermined value.
