EMF Calculation Question
EMF Calculation Question
(OP)
I need to calculate transmission line induced EMF for a project I am working on. There are two transmission lines in the same corridor where power flows in opposite directions.
The question is: Do I have to represent one current as negative since they are flowing in opposite directions?
Thanks in advance!

I need to calculate the neutral return current, for example A, B, and C phase at 0, 240, and 120 Degrees respectively, have 255.4, 257.5, and 250.3 amps, respectively. When you add the phasors you will have 6.4 amps of neutral current at 283.9 degrees.
My question, if you're still awake: Do I need to subtract 180 degrees from this neutral current, since it will flow the opposite direction of the phase current?

You can see this better if you just deal with a single phase case.
BTW, my transmission lines don't have neutrals. This would be distribution line.

180, 60 and -60 degrees with respect to the old A.
Then the neutral will be 6.413 A at +76.47 degrees.
If they are the same currents in opposite sense !
