In the case of a trefoil cable set cleated to a cable ladder. Is it necessary for the support arms of the cable ladder to be dimensioned for other mechanical forces than the weight of the equipment? The cable cleating is dimensioned to withstand the short circuit force between the cables...
Hi!
I have a question about positive and negative sequence impedances for cable, power lines, and transformers.
Is the positive (and negative?) sequence impedance for cable and power lines the same as rated R and X values?
And is the positive (and negative?) sequence impedance for a transformer...
