Abstract
PURPOSE: To improve operation efficiency by performing the discharging of electric charge to a high voltage cable after the end of a test in a short time, by providing a projecting discharge element to a high voltage exposure charge part to the high voltage cable to be tested.
CONSTITUTION: To high voltage cable 1 to be tested, DC generator 5 is connected via high voltage exposure charge part 10 consisting of lead lines 2 and 4, resistance 3, and shielding rings 6W9, thereby taking the dielectric test of cable 1. In this case, ring 9 over generator 5 is provided with projecting discharge element 11 made of a coil spring and while its outer circumference is covered with metal foil 13 during the test so that element 11 will not project out, a projection part is formed by elongating element 11 by nylon rope 12 after the end of the test. Consequently, discharging can be carried out in a short time.
