During which maintenance interval is the transmission loop tension checked?

During which maintenance interval is the transmission loop tension checked?

• A. Monthly
• B. Weekly
• C. Quarterly
• D. Yearly

Answer: (A)

Loop tension is a mechanical parameter that can drift as temperatures change, wind causes vibration, and components settle over time. Keeping it within tolerance is important to prevent loose connections, arcing, or conductor fatigue. Checking it monthly provides timely detection of drift without overburdening maintenance crews, while still catching gradual loosening early. Checking weekly would be unnecessarily frequent for something that doesn’t vary dramatically week to week; quarterly could miss progressive changes, and yearly could allow significant tension shifts before detection. So monthly is the appropriate interval to maintain reliable, safe operation.
