Answer / satish babu

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

Answer / r.nombri


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.
