Abstract

PURPOSE: To establish partial discharge in an insulating tissue so that deterioration judging data are accurately obtained by impressing a DC high voltage linearly upon the tissue in a manner to rise and fall.
CONSTITUTION: The voltage rectified at 1 at a low level is converted at 2 into a low voltage having a high frequency of several kHz and then is boosted at 3 to a high voltage so that it is impressed as a positive and negative DC high voltage upon a test piece 8 through a polarity changer 14 and a high voltage rectifying circuit 4. The voltage waveforms thus impressed are divided by a divider 7 and compared with and referred to the output voltage waveforms of a standard voltage generator 5 which is programmed in advance in a comparing and referring device 6. The control is made such that the low voltage rectified output level is increased and decreased in case of any shortage. And, the generator 5 commands the linear boost, hold at constant voltage and linear fall and inverts the polarity of the voltage. As a result, the test piece is supplied with the DC high voltage which repeats the linear variations to positive and negative polarities.
