How do determine the Size of a Droop Current Transfomer for
Paralleling of Two Generators, Say I need a Droop Current
transformer for a 600 kW generator need to be parallel with
a 800 kW generator, etc.

Answer Posted / 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

Is This Answer Correct ?    8 Yes 3 No
