What is the purpose of the Minimum Vegetation Clearance Distance (MVCD)?

• A. To set the highest distance for vegetation growth
• B. To ensure the shortest distance between conductors
• C. To prevent spark-over for various altitudes and operating voltages
• D. To regulate planting of trees near electric lines

Answer: (C)

The Minimum Vegetation Clearance Distance (MVCD) is vital for ensuring safety in the vicinity of power lines. Its primary purpose is to prevent spark-over, which can occur when vegetation is too close to conductors, especially under varying altitudes and operating voltages. This distance is calculated to accommodate the electrical, thermal, and mechanical stresses that can affect the conductors, ensuring that trees and other vegetation do not encroach upon the safety zone required to avoid electrical hazards. By maintaining the MVCD, utilities can safeguard against potential electrical faults or outages that can arise from overgrown vegetation coming into contact with live wires. This is important not only for the reliability of the power system but also for public safety, as it reduces the risk of fires or electrical injuries caused by fallen branches or trees.
