摘要：
Using testpieces of epoxy-resin moulding material without filter, which had an artificial hollow space, partial-discharge (PD) investigations were made with up to 80 degree C. In long-period tests a considerable shortening of life was found. Short-period tests have shown that in the case of temperature rise the mean apparent charge of the PD pulses increases greatly while the pulse frequency decreases. This important fact is confirmed by measurement of the PD interference voltage.
