    Thank you for the video. How could you tell the power was flowing in reverse? Thanks!

      Hi Lou, did you get a response from your question?, I 'm only watching this now, but I see there hasn't been a response. Did you get a private response from them? I would also like to know why he said the power was flowing in reverse. It doesn't make sense as power is delivered from the BUS out to line circuits.

      Hi Lou, I think if you take a snap shot of the voltage waveform in one instant of time, you'll see that phase A voltage is at 0 degrees, phase B voltage is at 270 degrees, while Phase C voltage is at 120 degrees. If all phases were rotating in the CCW direction which is standard, then we'll have an ACB phase sequence while normally it's ABC (this is very hazy guess) I think this is one way to tell that the power is flowing in the reverse direction. If others can correct me or have other insight to share which will reveal the direction of power flow per the waveforms, I'm all ears :)

    Great video ! The 50P2 Element seems to have activated at the inception of the fault but didn't result in the breaker tripping, why is that so ?

    • @Generalpac

      It's probably used for indication purposes and NOT in the trip equation of the relay :)

    Hi I am watching this video now, even though it is about one years old, I would also like to know why you said the power was flowing in reverse. It doesn't make sense as power is delivered from the BUS power bar out to line circuits. Would really appreciate if you could find the time to respond to my enquiry. Thanks in advance. By the way I really liked the tutorial and all the others. I have subscribed, but I cannot afford the packages as I am a full time student at NTNU EVU right now.

      Hi Stephen, the power is flowing in the reverse direction because our load is actually a wind farm (as stated in the paper) so it's generating power and selling back to the grid. Hopefully this help to clarify your question. You are absolutely right, without knowing the type of "load", power flowing in the other direction (into the transmission line) would be questionable
