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

Haven't really used a Droop CT. Droop is the decaying of
current from it's initial peak/input, so your trying to
maintain synchronism of two generators in parallel with a
droop CT. By which the Droop CT may be used to improve the
secondary output connection between the two generators with
respect to their rated VA, and kW.

Is there any Institution for giving M-tech in Electrical engineering for those who r in service? Give the details please.
