Dynamometers (or tension meters) are indispensable monitoring accessories in OHTL stringing because they:

• Ensure Sag Accuracy: They provide real-time, accurate readings of the tension being applied to the conductor. This is crucial for achieving the exact sag profile specified by engineering designs, which directly impacts the line's electrical performance, mechanical stability, and ground clearances.

• Prevent Over-Tensioning: By continuously monitoring tension, they alert operators to avoid exceeding the conductor's maximum allowable tension, preventing permanent deformation, damage, or even breakage.

• Optimize Efficiency: Knowing the precise tension allows operators to make fine adjustments to puller and tensioner speeds, optimizing the stringing process for efficiency and reducing unnecessary stress on equipment.

• Enhance Safety: Monitoring tension helps prevent unexpected line breaks or sudden movements, which can pose significant safety risks to personnel and equipment.

• Quality Control & Documentation: Digital dynamometers often come with data logging capabilities, providing a verifiable record of tension throughout the stringing process, essential for quality control and project documentation.
