In seq. network which are drawn here, u said that F is at higher potential then F' then the direction of current will be from F to F'. but you have shown the opposite direction.
Sir,I have one practical problem...in West Bengal Transco 132/33 trafo are 50 MVA Ynd1 with percentage impedance 12 percent.On LV side we connect 875 A earthing transformer. Red phase jumper of earthing transformer on no load bus found open .As a result neutral displacement relay(open dela PT voltage on 33 kv bus) tripped.Sir can u kindly calculate phase t ground voltage on 33 KV bus no load bus(only earthing trafo connected) when Earthing trafo one phase jumper open condition( considering infnite bus on 132KV side).....thanks in advance sir
Excellent explanation! A very useful lecture.
Thank you!
how did you calculate the value of alpha in phase voltage calculations sir?
Excellent lecture Sir. Thanks 🙏🙏🙏🙏

Yes I have the same question
Very well explained
If in a transmission line one phase is open then will zero sequence current will flow

wb mein bijli bhi aati hai kya?
Hello sir Imposiple name the book for power system analysis
Or rfernace
Thanks
@@lecturesinelectricaleng thank you vary much
🌹🌹😊
hi professor! could u activate the subtitles?
That was an awesome class!
@@lecturesinelectricaleng Ok! Thank u :)
