1.Application:
1)They serve to distribute the electric field gradient and reduce its intensity at the points of highest curvature.
2)They prevent the ionization of air (corona discharge) that can lead to power loss, noise, and damage to equipment.
3)They are commonly used in power transmission systems to enhance efficiency and protect the system's integrity.
