The Principles of Corona Discharge Static Removal Devices

The Construction of Corona Discharge Static Removal Devices

Voltage application systems utilizing corona discharge are constructed from: needle shaped electrodes that apply a high voltage; a high voltage power source; and grounding electrodes. Applying high-voltage to the electrodes produces a corona discharge on the needle tips.
When a corona discharge occurs and the air surrounding the electrode needles is broken down, ions are produced.
Using these ions, reverse-polarity static electricity is neutralized, and static is eliminated.
