Corona Effect

corposant Effect
One of the phenomena associated with all energized electrical devices, including high-voltage contagion lines, is corona. The topical anestheticized electric field near a manager backside be sufficiently concentrated to ionize ambiance close to the conductors. This can result in a overtone discharge of electrical energy called a corona discharge, or corona.
What is Corona?
? Electric transmission lines can generate a small do of sound energy as a result of corona.
?Corona is a phenomenon associated with all transmission lines. under(a) certain conditions, the localized electric field near energized components and conductors can produce a tiny electric discharge or corona that causes the surrounding air molecules to ionize, or undergo a slight localized change of electric charge.
?Utility companies r from each one to reduce the amount of corona because in addition to the impression levels of noise that result, corona is a power loss, and in uttermost(a) cases, it can damage system components over time.
?Corona occurs on all types of transmission lines, but it becomes more noticeable at higher voltages (345 kV and higher). beneath fair weather conditions, the perceptible noise from corona is minor and rarely noticed.
?During wet and wet conditions, water drops collect on the conductors and increase corona activity.



Under these conditions, a crackling or humming sound whitethorn be heard in the immediate vicinity of the line.
?Corona results in a power loss. Power losses desire corona result in operating inefficiencies and increase the damage of service for all ratepayers; a major concern in transmission line design is the reduction of losses.

Sources of Corona:
?The amount of corona produced by a transmission line is a function of the voltage of the line, the diameter of the conductors, the locations of the conductors in relation to each other, the elevation of the line above sea level, the condition of the conductors and hardware, and the local weather conditions.
