Corona electrode: After all the air surrounding the discharge electrode ionization, in the discharge electrode can be seen around the circle of light blue aura, this aura become corona. This is called the corona discharge wire pole. ESP achieve spark breakdown voltage is called breakdown voltage. Used in industrial gas purification ESP kitchen exhaust duct, usually stability, it can be negative corona higher operating voltage and current pole. ESP is used to purify the air intake ventilation and air conditioning, the general positive corona electrode. The advantage is that less amount of ozone and nitrogen oxides generated. Dust grounded as cathode discharge electrode connected to negative high voltage DC power supply.
