Hello.
I need to derive this equation (attached), can you help me please?

That's the equation for a two-pair terminal medium-distance power transmission line (20~100km).
I have no idea how to start it. Can someone guide me, please?

Hi MissP.25_5. Perhaps a clue lies in that bottom line. :wink:

Try a Pi network, with the two vertical limbs each a capacitor, and the horizontal part R + L.

So this leaves the earth as a straight-through link common to both ports.

Note, I haven't examined this further.

Oh, yes! That's right, the Pi network is the solution! I just solved it, thanks to you!
