Abstract
PURPOSE: To detect a defect before coating rapidly and securely by measuring the intensity of light discharged from a defect part by applying an AC voltage to a cable.
CONSTITUTION: While AC power supply 2 is connected to power cable 1 composed of conductor 11 and insulating layer 7 around it to apply an AC voltage, cable 1 is moved in conductive glass 3. If there wound be a defective part such as the void or internal conductive projection in cable 1, discharge light from the defective part is transmitted through conductive glass 3 and optical fiber 4. The transmitted discharge light is amplified by photo amplifier 5 and recorded by recorder 6. The defect in cable 1 can be detected by measuring light intensity by this recorder 6. Conductive glass 3 is used as an earth electrode and a voltage is applied to cable 1 only in the section where conductive galss 3 is installed.
