Abstract

PURPOSE: To avoid mis-measurement by restricting the production of local discharge not distincted from the partial discharge of the sample.
CONSTITUTION: The sample 16 is incorporated in the tank 18 and immersed in the insulation oil 17. The capacitor 20 and high impedance element 21 are immersed in the insulation oil 22 and contained in the tank 23. One end of the high impedance element 21 is connected to the power supply via the capacitor bushing 24, and another end if connected to the sample 16 via the spacer 19 at the high voltage lead 26, The low voltage terminal of the capacitor 20 is connected to the ground line via the primary winding of the pulse transformer 12. One end of the variable impedance element 6 is connected to the potential tap 25 of the capacitor bushing 24 and another end is connected to the ground line via the primary winding of the pulse transformer 11.
