corona effect การใช้

Manufacturers also adopt cheaper and smaller construction intended to avoid corona effect without series-connected sections, for example minimising enclosed air.
A non-catastrophic failure mode in this application is due to the corona effect : the air enclosed in the winding element becomes ionized and consequently more conductive, allowing partial discharges on the metallized surface of the film, which causes local vaporization of the metallization.
When in his solar form, Sunspot also has a corona effect, an aura that has been depicted in multiple ways, though two predominant conventions exist for its portrayal : one is that the air close to him manifests black globes of various sizes, reminiscent of Kirby dots, and the other is a unified field glowing a bright yellow or white.
The fact that the solar blasts were concussive in origin led directly into " X-Force " # 28, where Sunspot thinks of using them as a means of propulsion, and thus fly by blasting in the opposite direction of where he wanted to go initially leaving a slight trail behind him, but in later years, Roberto would learn to use the propulsion more subtly to appear to hover in place with no blast wake at all other than his usual " powered up " corona effect.
