摘要

讨论了在0.1 ~ 760 Torr压力和60 Hz交流通电条件下，针状接地平面电极在两种气体(空气和氩气)中的局部放电特性。该研究最重要的结论是，在低压下进行的所有测试中，PD电流脉冲的频率含量远低于常压下的频率含量。一般来说，低压下PD电流脉冲的频率含量超出了典型市售PD设备的检测范围。

Partial discharge characteristics at low pressures in dry air and argon

Characteristics of partial discharges (PD) in two gases (air and argon) under pressures in the range of 0.1 to 760 Torr, and 60 Hz AC energization are discussed for an energized needle grounded plane electrode arrangement. The most significant conclusion of the study is that the frequency content of PD current pulses for all the tests conducted is much lower at low pressures than at atmospheric pressure. In general, the frequency content of PD current pulses at low pressures is outside the detection range of typical commercially available PD equipment.
