| Abstract: | Corona is one of the important problems in the design and operation of transmission lines. Positive DC corona streamer characteristics under different air pressure and humidity conditions are obtained through the experiment and simulation. Voltage range, in which streamer discharge existed, increases with rising of air pressure and humidity, while streamer pulse amplitude measured and calculated by fluid model decreases as air pressure falls or humidity rises. This phenomenon is analyzed through the variation of electron density in the streamer channel. |

| Keywords: | positive dc corona streamer pulse air pressure humidity |
