In ref670 differential relay the display is not see its dark what is the problem

[@victr1994]

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.

[@baranitech1026]

you can try with usb adapter . but i am not sure 100%

Please make a video on testing of autoreclosurers in distance relay in detail

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

[@baranitech1026]

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

Sir in this video at 6:38 you mentioned differently Sir. I am confused

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

[@F13TUN]

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.
