Electrically isolating tuned mass damper
A system includes an electrical component, an insulating support structure supporting the electrical component at a first electrical potential higher than an electrical ground potential, and an insulating pendulum having a proximal end attached to the electrical component and suspended away from the electrical component to at least partially span the first electrical potential, the insulating pendulum further includes a tuned mass disposed at a distal end of the pendulum at a second electrical potential less than the first electrical potential. The system may also include a damping mechanism.
