corona discharge

• Явление, при котором жидкость (например, воздух), окружающая проводник, ионизируется, создавая видимое свечение или слышимое шипение, обычно возникающее при высоких напряжениях.

A phenomenon in which a fluid (such as air) surrounding a conductor becomes ionized, producing a visible glow or audible hiss, typically occurring at high voltages.

1. Electrical phenomenonC2formal

   A partial electrical discharge that occurs when a high voltage conductor is surrounded by a fluid (like air), causing ionization and a faint glow.
