Why does some noise come from the high tension line.

Question

Accepted Answer

Noise from high tension lines is caused by electromagnetic interference and corona discharge.

High tension lines carry high voltage electricity, which can cause electromagnetic interference.
Electromagnetic interference can generate noise in nearby electronic devices and equipment.
Corona discharge occurs when the electric field surrounding the high tension line ionizes the air, creating a buzzing or crackling sound.
Corona discharge can also produce radio frequency interference, which can be heard as noise.
Factors like weather conditions, line design, and equipment condition can affect the level of noise generated.

Accepted Answer

The audible noise that can be heard from high-voltage cables occurs because of the energy that is discharged. This discharge occurs when the conductor surface's electric field strength is greater than the breakdown strength of the air that is surrounding the conduct.
