Generation of voltage for each phase are same of a turbogenerator.Although the short circuit current flow when two phase of turbogenerator are shorted(where current can't flow without potential difference),why?
I have one ct of ratio 3000-2000/1 Amp its knee point voltage mentioned on name plate is 500-333/30mA-50mA at Vk/2. in secondary box there is three terminal named 1S1, 1S2, 1S3 then on which terminal obtained the knee point voltage ie 1S1-1S2 OR 1S1-1S3 & also specify the knee point voltage for the ratio 3000 from name plate.
