Consider two parameters to descide the CT ratings,
a) Primary current on the phase is 1050 amps,Consider No of
leads it has from the generator - If one cable is connected
your primary can be 1000A-1200A
If two leads are used , use only one lead as CT primary
then the CT primary can be 500-600 A
b) Your secondary can be 3A / 1A / 0.5A depending upon the
AVR used
