Maximum power transmission capability is achieved under conditions where____________?
Show answer Hide answer
Answer: A. corona losses are minimum
Explanation
Operating transmission lines near conditions that minimize corona losses ensures maximum power transfer efficiency. Excessive corona discharge wastes electrical energy and limits the overall power capacity. Minimizing these atmospheric losses preserves voltage levels required for optimal power transmission. Corona loss occurs when high electric fields ionize surrounding air near conductors. Factors influencing corona include conductor surface condition, spacing, and operating voltage levels. Engineers use bundled conductors to reduce surface electric field intensity and limit losses.
High-voltage transmission lines span vast distances where efficiency dictates operational economic viability. Controlling power loss prevents localized heating and radio interference near transmission corridors. Maximizing power capability without waste is crucial for modern electrical grid management. High line reactance generally impedes maximum power transfer capability rather than enhancing it. Sending end voltage magnitude alone does not guarantee efficient or maximum power delivery. Higher receiving end voltage can restrict power flow depending on phase angle differences.
