Corona Effect On Transmission Line | Not Covid One #technology #engineering #electronics

The corona effect, in the context of transmission lines, refers to the phenomenon known as corona discharge. This occurs when the electric field strength around a conductor is sufficiently high to ionize the surrounding air, resulting in a faint glow or discharge. The corona effect can have both positive and negative impacts on transmission lines. On the negative side, it leads to power losses due to the production of ozone and heating of the surrounding air, and it can generate radio frequency interference (RFI) that may affect communication systems. However, on a positive note, corona discharge can sometimes help reduce transient overvoltage or surge voltages in the transmission system.
Several factors contribute to the occurrence of the corona effect. High voltage is a significant factor, as the phenomenon is more likely to happen at elevated voltage levels. Additionally, the size and shape of the conductor influence the electric field distribution, affecting the likelihood of corona discharge. Atmospheric conditions, such as humidity and air density, also play a role.
To overcome the corona effect, various strategies can be employed. Increasing conductor size helps distribute the electric field over a larger area, reducing the intensity of corona discharge. Modifying the conductor shape or using bundled conductors can also alter the electric field distribution, minimizing the corona effect. Operating transmission lines at lower voltage levels, when feasible, can mitigate corona discharge. Additionally, improving the insulation of transmission lines is crucial for minimizing the impact of the corona effect.
In the ongoing efforts to optimize transmission line performance, engineers and researchers continually explore innovative designs for both conductors and insulators. Regular maintenance and monitoring are essential aspects of ensuring the efficient and reliable operation of the transmission system, considering the complexity of the Corona effect and its various influencing factors.
