摘要：

Breakdown voltage of air gaps is strongly affected by atmospheric conditions such as temperature and humidity. Detailed information is available in the literature on the effect of atmospheric conditions on the ac breakdown. However, similar data on the dc breakdown characteristics, particularly at high humidities is scarce. This paper presents dc data on the effects of humidity and temperature existing in tropical countries. Humidity correction factor curves are presented for rod-rod and rod-plane air gaps.
