About the Topic
In this meeting you will learn about the various forms of conductor motion (Aeolian vibration, subspan oscillation, and galloping), and determine the best devices and practices to implement in order to alleviate the potential system damage caused by these motions. An outline of topics to be covered is below:
- Types of conductor motion
- Aeolian Vibration, Subspan Oscillation, Galloping
- Review of Aeolian vibration
- What is it, and why is it a problem?
- Stockbridge dampers - how they work
- VORTX Placement Software
- How to sign up, use, and interpret information
- Spiral Vibration Dampers
- Field studies analyzing the performance of Spiral Vibration Dampers over Stockbridge dampers on small conductors
- Subspan oscillation
- What is it, why is it a problem
- Different types of motion
- Considerations for different devices
- Cushion Grip Twin Spacers
- Cushion Grip Spacer Dampers
- Galloping
- What is it, why is it a problem
- Mitigation devices
- Air Flow Spoilers
- Detuning Pendulums
