Answer Posted / Amit Kumar Gangele
The diameter (d) and angles for shielding wire in overhead lines are calculated based on factors such as the voltage level, line length, ground resistance, and lightning stroke characteristics. The shield wires are usually arranged at specific angles (typically 30 degrees or 45 degrees) to provide a complete cage around the conductor.
