Transmission Tower Sides

09/07/2017 3:06 PM

Hi,

i am confusing in sides of Transmission Tower ,

1)which one is circuit 1 and which one circuit 2, is there any IEC standards or any thumb rules,

if i said that in generation power plant and its grid has two circuits, circuit-1 and circuit-2 , must be at side A and circuit-2 must be B side of the attached picture, ?

but when we reach to interconnection point of other side grid side A and Side B will be turn with respect to power plant grid and the Distribution grid on other side,

thanks

It is usually established by the Utility, per the conventions they decide to follow. There is normally some logic to it, but there is not an international "standard" because the line configurations and paths can vary and the philosophies for how to orient them can differ. Find out what convention your local electrical utility uses, and follow it closely. And pay attention to orientation of phases as well as circuits, whether they are arranged vertically or horizontally on the structures.

...and don't forget any barrel transitions that might be embedded in the transmission lines! That's why you check, recheck, and check again when commissioning/phasing all new/rebuilt circuits.
