Which outcome occurs when ice accumulates in an overhead power conductor?

💡 Explanation

Increased line sag develops from the added weight of the ice, causing mechanical stress; line sag occurs because the additional weight increases tension, therefore line sag happens rather than optimized transformer efficiency or decreased resonance from conductor shape changes.
