Abstract
In an insulation coated conductor inspection method for inspecting an electrical insulation characteristic of an insulation coated conductor in a coil formed by winding the insulation coated conductor, the coil is disposed in a test container, an internal pressure of the test container is reduced, an electrodes are provided so as to face the coil with a gap therebetween, an alternating-current voltage is applied between the electrodes and the coil, a generation frequency of a discharge that is generated between the coil and the electrodes upon application of the alternating-current voltage is measured, and the coil is determined to be a non-defective product having a superior electrical insulation property when the generation frequency of the discharge is higher than a reference generation frequency and determined to be a defective product having a defective electrical insulation property when the generation frequency of the discharge is lower than the reference generation frequency. A predetermined range is preferably set as a range in which a discharge charge amount is no greater than 100,000 (pc).
