What are ground loops?

Ground loops refer to really low sagging transmission conductors. They sag so much, they nearly form loops that touch the ground. They exhibit remarkable dynamic characteristics when the wind blows that no Stockbridge damper can overcome. The cure is proper sagging of the conductors during initial installation. See the following video of ground loops during high wind:

Marc.... do you have a video showing high-tension lines galloping as well? :)

What are ground loops and how can this be prevented?

Bobby whats you point here?

You display enough knowledge in your other threads to know the answer to the question you ask in this thread.

So what are you fishing for?

What is your specific question? Ground loops in data systems or sound systems or premises wiring systems or perhaps we are back to substations?

That's really good.:grin:

The requirement of NEC to bond at the service equipment neutral and ground while neutral and ground is already bonded in the transformer. Will there be ground loops in this situation?

It is very possible to have circulating currents on the ground system IF, there is any metallic connections between the transformer pad/vault and the main service electric room or if the EC connects his electrode to the utilities electrode.

But if you are asking if a flamer carries current between the two? I doubt it.

What is a flamer?
