ABSTRACT:
Control of high voltage is effected using apparatus having a high impedance generator, the output being connected to a first member of low radius of curvature and a second member. The two members are spaced apart by a gas gap so that when the voltage between them exceeds a threshold value corona discharge across the gas can occur. Such apparatus is particularly useful in controlling voltage and hence the size and size distribution of liquid droplets in electrostatic spraying apparatus.
