Interference in radio astronomy, where it is commonly referred to as radio-frequency interference (RFI), is any source of transmission that is within the observed frequency band other than the celestial sources themselves. Because transmitters on and around the Earth can be many times stronger than the astronomical signal of interest, RFI is a major concern for performing radio astronomy. Natural sources of interference, such as lightning and the Sun, are also often referred to as RFI. RIV = Radio Interference Spannung Suchen Sie nach einer allgemeinen Definition von RIV? RIV bedeutet Radio Interference Spannung. Wir sind stolz darauf, das Akronym RIV in der größten Datenbank mit Abkürzungen und Akronymen aufzulisten. Radio interference in UHV AC substations mainly comes from corona on such equipment as busbars, fittings, and insulators. When the electric field strength on the surface busbar, fitting, and insulator and other energized conductors in the switchyard exceed the critical value, resulting in ionization of surrounding air followed by corona discharge, radio interference is stimulated.

Introduction: One of the phenomena associated with all energized electrical devices, including high-voltage transmission lines, is corona. The localized electric field near a conductor can be sufficiently concentrated to ionize air close to the conductors. This can result in a partial discharge of electrical energy called a corona discharge, or corona.
