Partial discharge tests The tests were carried out at ambient temperature and high temperature in accordance with IEC 60885-2, the sensitivity being 5 pC or better during the tests. The sensitivity is 1.3pC during these tests. The test voltage shall be raised gradually to and held at 112kV for 10 s and then slowly reduced to 96kV and the partial discharge tests were carried out at 96kV. At high temperature the test shall be performed on the sample at a conductor temperature of (95 100) 3.2 !"#$ GB/T 11017 !"#$$%&'( 100) 8h ! 16h 20 ! !"# ! !"#$%&'()*+,(95 !"#$% 128kV !"

The conductor temperature shall be maintained with in the stated temperature limits for at least 2 h of each heating period. This shall be followed by at least 16 h of natural cooling. The cycle of heating and cooling shall be carried out 20 times. During the whole of the test period a voltage of 128kV shall be applied to the sample. !"#2h !"#$%&' .
