    we have cmc 256-6 omricron relay test kit at our site. it has only host interface. Can we connect to pc using parallel to usb adapter or we must use the cmusb-p cable supplied by omicron? please reply.

    For reverse Vby is a reference 90(Vby)+20(RCA) = 110 is a MTA angle... pls reply. I think u made mistake in this video.
    And the operating region for reverse is 30 - 90 - 190 degrees inbetween.
    Kindly reply sir. If I am wrong pls correct me

      for Reverse. Ir start from 180 and its ref with VYB so operating region is 80 to 240 thank you

      For #R phase fault in reverse condition....
      For self Pol, Ref(-Ir) =180 deg
      Then 180 - 20 = 160 is a MTA
      So that we will get,
      Self polarization
      80 - 180 - 240 (Operating region)
      For Cross Pol, Ref(Vby) = 90 deg
      Then 90 + 20 = 110 is a MTA
      So that we will get,
      Cross polarization
      30 - 90 - 190 (Operating region)
      Sir Pls reply If am wrong
      Thanks for your previous reply

    You ve mistaken unintentionally.😂 You should say make 45 from VYB since its the reference not from IR as you said .. ie -90 deg+45 deg =-45.
