Forgive my ignorance here as I am an Electrical Engineer, but I have a question regarding using A-Frame bus between rigid bus pipes in a substation. Are these A-Frames considered structural, the same as an insulator? If so how are you calculating the force on the lower bus? Is there anyway to do...
At any of our substations, we can measure current on the structure ground wires. This is to be expected as the transformer is unbalanced, so we are seeing current from the neutral. My question is, how does this current flow? What is the path? It would seem to me that the structure would not...
