Learn how corona in transmission lines depends on rain, conductor surface and bundle geometry, and why noise cannot be judged from conductor area alone.
Understand the ABC cable neutral messenger: neutral current, bundle support, bare and insulated designs, clamp compatibility and conductor identification.
Compare aeolian vibration and galloping in overhead conductors: motion, fatigue, clearance risks and why damping devices need mechanism-specific verification.
Calculate overhead conductor sag with a worked SI example. Understand horizontal tension, mass conversion, catenary checks and the limits of a simple formula.
