Read the datasheet. There should be the information about precision.Will it be precious enough to measure up to 100A AC current?
One advantage of a CT is that you can put a bridge rectifier before the burden resistor and then your adc only has to measure unipolar (all +ve ) half cycles with respect to ground.

Hi,
before it was 100A , now it is 1000A.
You ask if it is precise enough, but you don´t say what precision you need.
If you use a low ohmic burden, then the dissipated power is also low.
Your posts lack a lot of informations and specifications. So it´s impossible to give good answers.

If all the "big fella" current transformers normally have a ratio to provide a standard 5 amps in the secondary, it should be possible to feed that five amps through a second much smaller current transformer mounted on the circuit board, to generate 5mA or 50 mA.
The power loss would then be negligible, and the small CT could be mounted up close to your ADC for minimal noise pickup. Its a win/win situation.
