    A-frame bus in substations

    Ah thats very helpful thank you! Does it matter where the insulator is located or how many insulators are on the bottom bus or is it safe to assume the applied force is equal across both insulators on the bottom bus?

    A-frame bus in substations

    Yeah when I'm referring to short circuit forces. That is interested that these are ignored to be honest. The short circuit forces can be quite high, and of course propagate through the A-Frame. Is IEEE605-2008 the best document to use when trying to calculate the cantilever force applied to an...

    A-frame bus in substations

    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...

    Current from transformer neutrals on ground

    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...
