The Effect of Humidity on a Corona Discharge in Air
ROYAL AIRCRAFT ESTABLISHMENT FARNBOROUGH (UNITED KINGDOM)
Pagination or Media Count:
The effect of humidity on a corona discharge in air is investigated and found to produce a decrease in discharge current of about 20 for a change in humidity from dry to saturated conditions at atmospheric pressure and room temperature. It is suggested that this effect can be used to measure humidity in applications where rapid response is essential and the need to compensate for moderate temperature and pressure changes can be tolerated.
