| Zusammenfassung: | PURPOSE: A method for insulation deterioration diagnostic in a high voltage cable is provided to reduce the dielectric breakdown accident of the high tension cable. CONSTITUTION: A point bonding connected to a high tension cable is separated(S420). An AC voltage is applied to the high tension cable(S430). The dissipation of the high tension cable is measured according to supplying the AC voltage(S440). An insulating deterioration of the high tension cable is diagnosed through a dielectric tangent(S450-S470). |
