What Is Corona Discharge?

Corona Discharge: “a discharge, frequently luminous, at the surface of a conductor or between two conductors of the same transmission line, accompanied by ionization of the surrounding atmosphere and often by a power loss.” Lost you yet? That’s the dictionary definition.

Let us break it down. When you observe a solar eclipse (without looking directly at it, of course!), that ring you see is called a corona, so it goes to reason that corona is snug at the surface. And the discharge is what causes the glow. Have you ever heard of Saint Elmo’s fire, the glow around a ship’s mast during a lightning storm? It is caused by corona discharge in the air. Or, did you know that a lightning rod works the same way? While fascinating to watch, you wouldn’t want to touch it!

Ozone is a byproduct of this corona discharge. So, without giving any trade secrets away, we can just say, that is the technology behind our ozone generators. And, it works!

Another technology that creates ozone is ultraviolet (UV) light. UV has shorter wavelengths. NASA explains the Northern Lights are caused by UV is moving along Earth's magnetic poles.

While corona discharge is capable of producing pure, strong ozone. That is especially true when using oxygen. The cells can last longer and it requires less energy. With UV, it is capable of producing smaller amounts. But, both have their place in ozone applications.
